It's not so important.

Yes, I know. XD

we need to see the code to solve it

ERR_INVALID_STOPS	130	Stops are too close, or prices are ill-calculated or unnormalized (or in the open price of a pending order). The attempt can be repeated only if the error occurred due to the price obsolescence. After 5-second (or more) delay, it is necessary to refresh data using the RefreshRates function and make a retry. If the error does not disappear, all attempts to trade must be stopped, the program logic must be changed.
ERR_INVALID_TRADE_VOLUME	131	Invalid trade volume, error in the volume granularity. All attempts to trade must be stopped, and the program logic must be changed.

Ok here is the first EA cross over I typed up, nothing special though a simple moving average cross over executing a BUY and SELL etc
