Por mas que modifico mis nivel de SL no consigo hacer que me funcione. Me podrian decir como solucionarlo. por mas que pruebo mil cosas me es imposible.
Como deberian quedarme las propiedades de experto?.

I think you are trying to trade one of the indices, and TP and SL levels are lot different for these. Also u cannot place very small and very small lot size.

I think first you try to place a normal order with Expert. See how much can be the lot size, TP and SL, then try to use it in your Spheretester.
