Commission in %

[connex]

I'm trying to do a backtest in where I want a comission based on a percentage.
As far as I can see there is no support for this setting.

Are there ways to work around this in a simulator environment?

Maybe a way to overwrite the current commission in an OnBarUpdate?

Is there a way to get this working with custom code, if so, where should I be looking?

Hello Connex,

Thank you for your post.

You would need to create you own logic that would calculate the percentage commission rate that you can then Print(); and check.

I understand I need to do it manually.

But is there a variable or function i could overwrite / call that is able to change the commision during the backtest itself?

Where should this "logic" be placed?

connex, would unfortunately not be aware of any undocumented workarounds to set this dynamically. You would need to basically run custom performance stats/calcs that would reflect your % commission approach then.
