My interpretation of how to code a robot using market buy and sell orders to cope with market validation. This framework deals with some checks that a trading robot must pass before it is published on the market. For educational purposes.

code example BUY

ask=MarketInfo(_Symbol,MODE_ASK);           bid=MarketInfo(_Symbol,MODE_BID);           sl=(OrderStopPips==0)?0.0:bid-ExtOrderStop;           if(sl!=0.0 && ExtOrderStop<StopLevel)              sl=bid-StopLevel;           tp=(OrderTakePips==0)?0.0:ask+ExtOrderTake;           if(tp!=0.0 && ExtOrderTake<StopLevel)              tp=ask+StopLevel;           GetLot=CheckVolumeValue(Lots);           if(!CheckStopLoss_Takeprofit(OP_BUY,ExtOrderStop,ExtOrderTake))              return;           if(CheckMoneyForTrade(GetLot,OP_BUY))              order=OrderSend(_Symbol,OP_BUY,GetLot,ask,10,sl,tp,"FrameWork",678,0,Blue);
