Need Help with EFS version 1

[Emerald King]

Hello to All,

I have a modified version of a Parabolic Entry/Exit system that I found on this forum.

My Problem is that I am trying to backtest this and the backtest doenst show the correct entry/exit prices.

This is just on forex data and I am sure that my problem lies with me not understanding how to construct the proper syntax to get the trade to reverse at the psar value.

Can someone take a look and point me in the right direction?

It is not reversing a trade when it hits a 50 pip drawdown.

Hello EK,

You are using the entry constants .MARKET/.THISBAR, which will use the open of the bar being processed for the entry. If you want to use the close of the bar as the entry use .CLOSE/.THISBAR. Or you could use the open of the next bar with .MARKET/.NEXTBAR.
