How do you calculate these values 9-11/8-12/11-9, etc... Can you show your trades history ?

Are you sure about that?

The OP does not use RefreshRates() in the code and it is quite possible that the loops could take some time to execute, therefore missing ticks.

So, on demo, a trade will be placed at the Ask price loaded when start() is called, no matter whether ticks have been missed or not?

Do you propose reducing slippage or no slippage at all?

Yes I am sure.

Even if the loops take too much time (which is possible here if trades history if very large), and your price doesn't correspond to actual price, you will get an Invalid price error(129).
