Hi Slawa.....tx for your answer....
but one more question.... is it the same way if we want to know the value of indicator in the previuos bars?
for example: I want to know the value of RSI on the last 2 or 3 bars from the current bar.....

This is how you do it in MetaTrader 4:

double rsi0 = iRSI(NULL,Period(),14,PRICE_TYPICAL,0);  // this bar
double rsi1 = iRSI(NULL,Period(),14,PRICE_TYPICAL,1);  // previous bar
double rsi2 = iRSI(NULL,Period(),14,PRICE_TYPICAL,2);  // 2 bars away
double rsi3 = iRSI(NULL,Period(),14,PRICE_TYPICAL,3);  // 3 bars away



I'm not sure about MT3, but it might be very close.
