Trigger

Hello tekitekiteki

I finally realized what is going on and it was thanks to our friend rubold member.
Thanks mate !!

That's right, in test mode bets you have to have the available banker responsible for all back and lay bets, even when they are made in the same selection.
The market feeder in terms of responsibility does not operate the way betfair can.

However in test mode I personally use a trick for this which is:

Imagine you want to test your strategy with a £ 1000 bankroll

So in test mode I put a £ 10,000 bankroll and adjust the stake, stop loss, stop profit percentages (if they are present in my trading) to use the values as if it were my only £ 1000 bankroll.

So my P / L and stop simulation is what I want but I have a huge bankroll where all the betting liability calculations can be done without any problem.

I hope I helped and I apologize for not having answered more concretely before, is that I was even lost without realizing it.

My mistake only!
Thank you

Thank you for the answer.
Now it's clear how to deal with the problem in the test mode.
Would I have the same problem with real account? In this case it would be problematic to put 10'000 instead 1'000.
