Asking help for a coding...
- Don't double post.
- Help you with what? You haven't stated a problem. Just code it:
double emaPrev = iMA(..., i+1); double cloPrev = Close[ i+1]; double emaCurr = iMA(..., i ); double cloCurr = Close[ i ]; bool wasAbove = cloPrev > emaPrev; bool isAbove = cloCurr > emaCurr; bool isCross = wasAbove != isAbove;

I am new to coding and still try to learn it. Can somebody tell me how to do this. The case is there is a EMA with period of 9 and I need to get a signal after crossing that EMA from current candle close. I appreciate your kind help. thank you.
hello, you can see the sample of moving average built in on your MT4, there was a logic for it
//+------------------------------------------------------------------+ //| Check for open order conditions | //+------------------------------------------------------------------+ void CheckForOpen() { double ma; int res; //--- go trading only for first tiks of new bar if(Volume[0]>1) return; //--- get Moving Average ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0); //--- sell conditions if(Open[1]>ma && Close[1]<ma) { res=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,0,0,"",MAGICMA,0,Red); return; } //--- buy conditions if(Open[1]<ma && Close[1]>ma) { res=OrderSend(Symbol(),OP_BUY,LotsOptimized(),Ask,3,0,0,"",MAGICMA,0,Blue); return; } //--- }

if(Volume[0]>1) return; | For a new bar test, Bars is unreliable (a refresh/reconnect can change
number of bars on chart,) volume is unreliable (miss ticks,) Price is unreliable
(duplicate prices and The == operand. - MQL4 forum.) Always use time. New
candle - MQL4 forum
I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times. |

let's see when market open in Monday, just check MT4 on M1 or M5, is that volume give us information about Tick ? or Trade of volume actually ?

Am I correct ?????? Stop double posting.
