How to test with 0 spread?

 

Hi,


I don't want to test a certain strategy. More like to prove if an event1 leads to a certain outcome. Therefore I would like to run some tests but without any spread to not skew the result.

Now it seems that a input of '0' in the relevant spread field in the strategy tester leads to the current spread or anything else but not zero spread.

What has to be done to cut out the spread in backtesting? Thank you.
