To make things clear, I made a flow chart: And there are two questions inside: Question1: If manually changed the balance, should the “Balance” value in the code be changed accordingly? Question2: Will close some trades by hand harm the startegy? What is the correct way to handle this? Attached Files Last edited by AdamWu; 07/29/20 03:01.

(Unless you override this behavior using the SET_PATCH broker command.) Now, if you want to simulate it in a backtest instead, manually changing the Balance value does not work. Instead, consider applying credits and debits to your account using enterTrade(). I explain how to do this on my blog: https://www.vitaltrades.com/2020/07/14/adding-exact-fee-and-credit-calculations-to-zorro/ www.vitaltrades.com - andrew@vitaltrades.com

For example with proper money management and with a diversified portfolio. To make sure my strategy is prone to margin calls, I've included this into my code: Code if(Equity - MarginVal < 0) { printf("\n*CRITICAL*"); printf("\nMargin Call: Margin (%.2f) >= Equity (%.2f)", MarginVal, Equity); printf("\nTheoretical Equity should be: 'Balance(%.2f) + WinValTotal(%.2f) - LossValTotal(%.2f)'", Balance, WinValTotal, LossValTotal); quit()//(Optional); }

If there are 30 open positions, it is not easy to handle by hand. How about red alert earlier but don't quit the strategy. Add some money and let stragtegy go on?

In case you receive a margin call, it's too late to fund your account anyway. By using a brokerCommand -> GET_POSITION (see https://zorro-project.com/manual/en/brokercommand.htm), you can validate which positions are still active. Yeah, you can add an alert warning. For example when your margin reaches 80% of your available funds: Code if(MarginVal / Equity > 0.8) Last edited by Grant; 07/30/20 09:46.
