Selecting input data, minimum balance, and leverage for the "Onyx MT5" and "Onyx MT4" advisors

The "Onyx MT5" Expert Advisor consists of four set blocks with different settings that operate independently. Buy Stop and Sell Stop pending orders are placed at the previous day's high and low.

For the Expert Advisor to function correctly, it's necessary to select the correct balance between deposit, leverage, and input parameters. The tables below help you select the appropriate set file based on the lot calculation method.

Lot calculation parameters:

"MinLot": valid if Lot = Fixed_Lot.

"Multiplicity_for_Lot": applied if Lot = Dynamic_Lot and Lot_calculation_method = Lot_from_Balance. Every Multiplicity_for_Lot deposit unit increases the Lot by 0.01. For example: Balance = 1500, Multiplicity_for_Lot = 100, Lot = 0.15.

"Risk percent (%) of equity": applied if Lot = Dynamic_Lot and Lot_calculation_method = Risk_percent_of_equity. The Lot is calculated so that when all positions are closed by stop-loss (the maximum possible minus profit), the drawdown does not exceed the declared percentage of available funds.

You can use a files.set that matches your leverage and balance (screenshots with the test results of the files.set data are shown below):

It's important to check the balance, leverage, and input parameter values ​​during testing. This can be done by enabling the "Risk Management Info Panel" when testing in visual mode. The panel will notify you of any discrepancies. It is also recommended to keep the panel enabled when trading on a live account. If the "margin" changes over time, you will see this in the message.

For example:
At the beginning of 2025, with a price of 2500 (XAUUSD), leverage of 1:100, and a lot size of 0.01, opening one pending order requires $25 in available equity.
Currently (beginning of 2026), the price of gold is 5000, and the required equity is $50.
With leverage of 1:500 and a lot size of 0.01, the required equity is $10.

When testing, set the required deposit and leverage :

For ease of translation from English using a translator, the messages in the panel are numbered, and I will duplicate them here:
