I am getting tons of this error "Your order has been rejected due to validation failure. order amount is empty or zero" on my strategy this month (August). https://www.dukascopy.com/strategycontest/?action=blog&trader=pipx&month=201508

The strategy uses a custom trailing stop after n pips (onTick). I have no idea why the system is rejecting this while back testing for a year on VJForex and JForex worked OK.

I also don't get why, the current open position was filled as 1.050M and the strategy requested 5M.

I appreciate any insight on this.
Thank you

Greetings.

Please provide strategy and steps to replicate the problem.

Best regards, Support Team.

Hello,
I was able to fix this by moving the SL function from tick to 1 min. It works fine now, and I also learnt that not using slippage leads to partial fills

Same about slippage and partial fill. Please provide strategy and steps to replicate the problem.
