Whether you're just starting with crypto bots or you're already deep into automation, one truth remains: no strategy performs well without tuning. That’s where backtesting comes in.
In this guide, we’ll walk through everything you need to know about backtesting DCA strategies in 3Commas — from understanding what backtesting actually is, to how to test different indicator setups and averaging logic for the most consistent results. This isn’t a technical deep-dive; it’s a clear, practical playbook based on real workflows and what actually works inside 3Commas.
What is Backtesting?
Backtesting is the process of testing a trading strategy on historical market data to see how it would have performed. It gives you insight into the behavior and effectiveness of a strategy before you risk any real funds.
In 3Commas, this becomes especially useful when working with DCA bots. While DCA as a concept is simple — placing regular buys at falling prices — 3Commas allows you to go far beyond that by customizing entry conditions, indicator filters, and averaging logic. Backtesting lets you explore how different combinations of these parameters would have played out in past markets, so you can confidently run your strategy live.
Why is Backtesting Important?
Test Strategy Variations Without Risk
There are countless ways to set up your DCA bot — using RSI, MACD, MFI, TradingView signals, or price-based triggers. Each combination behaves differently depending on the market. Backtesting helps you explore these setups safely and see what performs best.
Optimize Your Parameters
Fine-tuning your strategy can make a huge difference. A 5-point change in your RSI threshold, or a tweak in your safety order step percentage, can drastically alter your results. Backtesting shows you the impact of these changes without needing to wait weeks in real time.
Understand How Your Strategy Reacts to Markets
Backtesting gives you context: how does your bot behave in a bull market? A sideways chop? A flash crash? These insights help you avoid surprises when running live.
Reduce Guesswork
Instead of building a bot based on what “sounds good,” backtesting gives you real data to guide your decisions. It removes emotion and lets you work with facts.
Build Trust in Your Strategy
Seeing your setup succeed across different market phases helps you stick with it when things get shaky. Confidence comes from preparation — and backtesting gives you that.
How DCA Strategies Work in 3Commas
Before diving into backtesting, it’s important to understand how DCA bots function inside 3Commas.
A typical DCA bot works by placing a base order followed by a series of safety orders. The base order opens the initial position, while safety orders are used to average down if the price moves against the initial entry. When the price recovers to a predefined target, the full position is closed for profit.
What makes 3Commas powerful is the ability to customize:
Base order entry conditions – using indicators like RSI, MACD, Bollinger Bands, or custom TradingView signals.
Safety order triggers – placed at fixed price deviations or based on indicator signals.
Order size scaling – adjust the size of each safety order using volume multipliers.
Step scaling – widen or tighten the distance between safety orders dynamically.
Take profit targets – set fixed or trailing take profit levels.
This level of customization opens the door to strategy optimization — and that’s exactly where backtesting becomes essential.
Backtesting Workflow: A Practical Step-by-Step Approach
To find a well-performing DCA setup, it’s best to follow a structured process. The idea is to start simple, understand how each parameter behaves, and gradually build toward a setup that performs consistently.
Here’s a reliable step-by-step workflow anyone can follow in 3Commas:
Step 1: Choose a Reliable Trading Pair
Start by selecting a trading pair that you trust and are comfortable trading — ideally one you’re familiar with in terms of price behavior, volatility, and news impact. This helps you better interpret the results and spot when something doesn’t look right.
If you're completely new to the market, it's a good idea to begin with a liquid and well-known pair like BTC/USDT or ETH/USDT. These pairs have stable volume and smoother price action, making your first backtesting experience more consistent and easier to evaluate.
Later on, once you’ve found a setup that performs well, you can test the same strategy on different pairs to compare results and broaden your bot coverage across the market.
Step 2: Choose the Market Period You Want to Test
Before setting up any indicators or strategy logic, it’s important to decide which type of market behavior you want to test your DCA strategy against. Crypto markets move in distinct cycles — bullish, bearish, or sideways — and a strategy that performs well in one environment might fail in another.
In 3Commas, when running a backtest, you can choose the time period for testing. This gives you the flexibility to test a strategy specifically during:
A bull market to check trend-based performance
A bear market to stress-test recovery and averaging logic
A sideways market to evaluate if entries are still meaningful
Choosing a timeframe helps you tailor your DCA parameters accordingly. For example, in a long downtrend, you may want to use more safety orders, wider price steps, or more aggressive scaling to keep the bot active and safe. In a stable or rising market, the strategy might rely more on tighter entries and fewer averages.
By aligning your backtest window with the kind of market you want to prepare for, you’ll gain more realistic insights — and be able to fine-tune your strategy with purpose, not guesswork.
Step 3: Set and Refine a Simple Entry Condition
Start by selecting a single, familiar indicator to define your base order — such as RSI crossing below 30, MACD crossover, or any other basic condition you know well. Keep the logic minimal and run an initial backtest to confirm that the strategy can generate trades.
After the test runs, 3Commas will display a detailed backtest report with:
A chart showing when and where trades were executed
A trade log listing each position opened and closed
The total number of closed deals
Take some time to review these outputs. Check whether the entries happen in logical spots — for example, after clear dips or reversals — and whether the trade history matches your expectations. If the strategy doesn’t open any trades, or they seem random or mistimed, your condition may need adjusting.
Once entries look consistent, you can begin tweaking the indicator's parameters — like modifying thresholds or lookback periods — to fine-tune the setup. This process helps you create a solid, reliable entry condition as the foundation of your DCA strategy.
Step 4: Fine-Tune and Expand Your Entry Conditions
After confirming that your strategy produces entries, the next step is to refine the indicator settings and decide whether you want to introduce a secondary condition for more control.
Start by tweaking the parameters of your chosen indicator. For example, with RSI, you might adjust the threshold (e.g. from 30 to 35) or the period length to make it more or less sensitive. Every change can affect how often your bot enters trades and how it reacts to price movement.
After each adjustment, run a backtest and review:
Are trades being triggered too often or too rarely?
Are entries happening at logical price points?
Is the number of trades reasonable for the chosen market phase?
Once you're satisfied with the basic logic, consider adding a second condition to filter or confirm entries. For instance, you can combine RSI < 35 with MACD, or with a BB% trigger. Adding another indicator can reduce noise and improve the timing of your trades — especially in sideways or choppy markets.
The key is to build the entry logic one layer at a time, running small tests after each change. This allows you to stay in control of the strategy’s behavior and avoid creating overly complex logic that becomes difficult to interpret.
Step 5: Optimize Your Averaging Logic
Once your base entry is working well, it’s time to focus on how your bot handles averaging down—the heart of any DCA strategy. In 3Commas, you have two main ways to trigger averaging orders: using price deviation (e.g. -2% from the last order), or combining with indicator-based conditions (like RSI dropping below a certain level again).
Start by testing both approaches separately. Price-deviation averaging is simple and consistent, while indicator-based averaging adds precision—placing safety orders only when technical conditions align. The process of selecting and tuning indicators for averaging is the same as with base entries: test one at a time, adjust parameters, and check how the bot behaves across different market phases.
If indicator-based averaging gives you better control, go deeper by testing familiar signals one by one. If price-deviation logic feels more reliable, you can enhance it by experimenting with scaling—adjusting how aggressively your bot averages as the price drops. Specifically, try modifying:
Step scale – how much the distance increases between each safety order
Volume scale – how much the order size increases with each step
Run backtests for each configuration and observe the output chart, logs, and stats closely. Pay particular attention to maximum floating drawdown — it shows how deep the bot's unrealized losses got during each trade. A strategy might close with profit, but if the drawdown was too large, it could be risky to run in live conditions.
The goal is to build a setup that feels balanced—aggressive enough to recover, but not so heavy that it overloads your capital in a short move.
Step 6: Review Trade Behavior and Metrics
Once you've run a backtest, the most valuable part comes next — interpreting the results. 3Commas provides a detailed summary with metrics, charts, and full trade logs that help you understand exactly how your strategy behaved.
Start by checking the high-level statistics:
PnL and ROI show overall profitability — useful, but not the full picture.
Win rate and number of trades closed give insight into frequency and reliability.
Average trade duration and max trade duration reveal how long your deals stayed open — helpful for spotting stuck or overly slow recoveries.
Max. floating drawdown is especially critical — it shows how deep the bot's unrealized losses reached during a trade. Even if all trades were closed profitably, a high floating drawdown could signal serious risk in live trading.
Total fees help you measure how much performance was eaten up by trading costs.
Next, dive into the trade log, which lists every deal in detail — including the exact timestamps, prices, and volumes for base and take-profit orders. Use this to cross-check whether entries occurred in logical market moments, and whether averaging behaved as expected. Look for unusual spacing, erratic base orders, or repeated entries too close together.
Then review the chart overlay, which shows where trades were opened and closed. Make sure the entries align with visible market dips, trends, or reversals based on the conditions you set. If entries feel random or poorly timed, your logic may need refinement — regardless of what the ROI says.
Don't just chase high profits. A good backtest is one where the entries make sense, the risk is controlled, and the bot behaves in a way you’d trust with real funds. Clean, logical trade behavior often beats aggressive setups with hidden risks.
Step 7: Repeat the Process Across Market Cycles and Pairs
A single backtest on one pair during one time period gives you limited insight. To build a strategy you can trust, it’s essential to repeat the entire process across multiple market cycles, different assets, and even different historical periods within the same market structure.
Once you've found a promising setup for a particular cycle—like a long downtrend on ADA/USDT—go back and search for other periods in history with similar conditions. Apply the same parameters and test again. If your strategy performs well across different instances of the same type of market behavior, that’s a strong sign of reliability.
Then, test across other pairs. Even if the setup works great on ADA/USDT, you might get very different results on pairs like ETH/USDT or LTC/USDT. Each asset has its own volatility, liquidity, and behavior around indicators. Repeat the process: tune the base entry, evaluate averaging, monitor drawdown, and check trade logic.
By testing across different pairs, cycles, and points in history, you’re not just optimizing — you’re building a library of strategies, each suited for a specific type of market. That’s how you go from “something that worked once” to a consistent, multi-scenario trading plan.
How to Read Backtest Results (And What Actually Matters)
Once you’ve run your backtest and reviewed the chart and logs, the final step is knowing how to make sense of the numbers. It’s tempting to focus on ROI, but the real value lies in what the underlying metrics tell you about risk, behavior, and reliability.
Here’s what to look for — and how to read between the lines:
PnL and ROI
This shows your total profit and return on investment over the test period. It's a good starting point, but not enough on its own. A high ROI can be misleading if it came with massive risk or inconsistent performance.
Max Floating Drawdown (MFD)
This is one of the most important stats. It tells you the largest unrealized loss your strategy experienced during a trade — essentially, how deep underwater the bot went before recovering. A profitable bot with -25% floating drawdown might survive in backtest but panic you in live trading.
Max Drawdown (MDD)
If MFD shows floating losses during active trades, MDD reflects the worst drop in your total account value over time. In many cases, it will be equal to or lower than MFD in DCA strategies. It’s a signal of how much your equity dipped before climbing back.
Trade Count and Win Rate
More trades doesn’t always mean better. A very high win rate (like 100%) can sometimes indicate an overly safe or overly tight setup — which might break down in live conditions. Fewer trades may be fine if they’re consistently placed and recover quickly.
Average Trade Duration
This tells you how long the bot stays in a position. A long average duration might mean slow recoveries or inefficient averaging logic. Combine this with deal logs to see which trades dragged and why.
Max Averaging Orders Used
This shows how deep into your DCA ladder the bot had to go. If it's constantly using the maximum number of safety orders, that’s a warning: you may need to adjust step size, volume scale, or entry logic to reduce risk.
Fees vs Profit
Always look at total fees paid. In many strategies, especially with small profit targets, fees can eat up a significant chunk of gains. If your average profit per deal is $1.50 and you're paying $0.40 in fees, that’s nearly 27% of profit lost per trade.
Visual Trade Placement
Go back to the chart. Do entries actually make sense? Are trades being opened at proper dips, reversals, or oversold areas — or are they scattered without logic? If the stats look good but the trade placement looks chaotic, it’s a red flag.
Backtest results are more than just a report card — they’re a diagnostic tool. The best-performing bots aren’t the ones with the flashiest ROI, but the ones that behave predictably, recover gracefully, and keep you in control. Trust the logic, trust the data, and let the metrics guide your fine-tuning.
Final Thoughts & Tips for Smarter Backtesting
Backtesting is more than just a tool — it’s a mindset. It’s how you go from hoping your bot will perform, to knowing how it behaves in different markets, on different pairs, with different setups.
If you’ve followed the steps in this guide, you’ve already done what most traders don’t: you’ve built your strategy methodically, with logic, testing, and iteration.
Here are a few final tips to keep you sharp:
Backtesting Mindset
Test with purpose. Don’t just tweak values randomly — understand what each change is meant to solve.
Think in market phases. A strategy that crushes a bull run might sink in a sideways chop. Know when and where your bot thrives.
Trust behavior over ROI. If the entries make sense, the drawdowns are controlled, and the strategy reacts logically — that’s a winning setup.
Backtesting Best Practices
Backtest one change at a time so you can isolate what’s actually helping or hurting.
Always review floating drawdown and entry logic on the chart — they tell the real story behind the numbers.
Use similar historical periods to confirm your strategy works in more than one place.
Once a setup works, try it on other pairs and environments to validate its range and flexibility.
Keep a log of your tests and results so you don’t waste time retesting what you’ve already ruled out.
Your Next Steps
Use this guide as your personal blueprint. Whether you’re building your first bot or refining an advanced setup, backtesting gives you the edge of clarity, control, and confidence.
Now go test, iterate, and build the DCA strategies you can actually trust — backed by real data, not guesswork.
