What Has Changed?
Previously, when using percentages for both Max Investment Usage and Volume per Order, each new order volume was calculated based on the remaining available balance after previous orders were executed. This meant that every subsequent order was smaller than the last, as the available funds diminished with each trade.
Now, the order volume for each executed signal is calculated from your initial Max Investment Usage and stays constant throughout the bot’s operation.
Example:
If you allocate $1,000 with 80% Max Investment Usage and set Volume per Order to 20%, the bot will execute 4 orders of $160 each until the allocated $800 is fully used.
Order # | Old Order Size ($) | Remaining Balance ($) | New Order Size ($) | Remaining Balance ($) |
1 | 160 | 640 | 160 | 800 |
2 | 128 | 512 | 160 | 800 |
3 | 102.40 | 409.60 | 160 | 800 |
4 | 81.92 | 327.68 | 160 | 800 |
5 | 65.54 | 262.14 | — | 800 |
Why Was This Change Made?
We made this change to improve reliability in your trading plans. Fixed order volumes give you a steadier, more transparent approach to position sizing, helping you avoid unexpected decreases that can affect overall performance.
How Realized Profit and Loss (rPnL) Affects This
Although order sizes remain fixed relative to the initial investment, your realized Profit and Loss (rPnL) will still affect your actual available balance. Profits increase and losses decrease the effective funds your bot can use, which might impact order execution in practice. It's important to monitor your rPnL to understand how it influences your bot’s trading capacity.
What Should You Do?
Review your Max Investment Usage and Volume per Order settings to ensure they align with your desired trade sizing.
Remember that while order sizes remain fixed, rPnL may still affect the balance.
Adjust your risk management accordingly, considering that your bot won’t reduce order sizes automatically with each trade.
Summary
Old method: Order volumes decreased after each executed order based on remaining balance.
New method: Order volumes stay fixed, calculated from initial investment.
rPnL impact: Realized profits and losses affect your available balance and order execution.
