Hi
i ve got the following code that scans the bars on a chart from right to left. What it does is to get the bar from the current TF i m looking at and get down to M1 timeframe and scan the bars there.
Eg if were looking at the H1 timeframe then the loop will get each H1 bar and get down to M1 timeframe and scan this 60 x M1 bars till the H1 bar its over.
Now my problem is that i cant find a way to change my code so to check for a specific period time (eg 14 Period, 21 Period etc).
By period i mean how many bars to calculate back...that extern parameter that many indicator has like MAs, RSI etc. eg 14RSI, 21SMA etc... i do not mean the timeframe period.
I'm only half understanding what y are trying to do and what your desired end result is, your variable names don't help .. . dt1, dt2, cndles, shift, etc it will help if you use more descriptive names.
This is a problem . . . .
shift = 1 + MathMod( TimeMinute(dt), (per) );
I assume shift is an int ? MathMod() returns a double and takes 2 doubles, so you give it 2 datetimes and use the result with an int ? why don't you use % ? in fact why don't you just us iBarShift () ?

thanks for your answer. I ll repost my code in a more complete form.
int start() { datetime dt,mdt,dt1,dt2; int i, j, k, candles, counted_bars,per,shift,total_1M_Bars,minBars; counted_bars = IndicatorCounted(); if (candles<0) return (0); candles=Bars-counted_bars-1; // Index of the first uncounted if (candles>history-1) // If too many bars .. { candles=history-1; // ..calculate specified amount } total_1M_Bars=candles*Period(); // maximum M1 bars. Limit for j i=1; // bar counter. ignore zero bar. Start from 1 eg. 1..99 // for 100 candles dt1=Time[i]; //set search from candle date (higher timeframe candle. eg. for H1 dt1=11:00, dt2=11:59 or for M15 dt1=13:15, dt=13:29 dt2=Time[i-1]-60; dtTemp=dt2; found=-1; tries=0; //************** CALCULATE M1 SHIFT //Calculate shift on M1 timeframe while (found==-1 && tries<total_1M_Bars) //&&tries<maxBars to avoid endless loop { found=iBarShift( Symbol(), PERIOD_M1 , dtTemp , true ); if (found==-1) dtTemp=dtTemp-60; //search 1 candle (M1) to the left tries++; } shift=found; // Scan bars starting from right to left // while i<higher tf candles and while ( (i<=candles) && (shift < total_1M_Bars ) ) { dt=iTime(Symbol(),PERIOD_M1, shift ); //get datetime of current shifted M1 candle if ( dt1 <= dt && dt <= dt2 ) // if datetime of M1 bar (dt) is between the desired dt1 and dt2 then... { C= iClose(Symbol(),PERIOD_M1,shift); //just some calculations result=result+calculations(C);//just some calculations shift++; // go to the next M1 candle } else // we are outside the current (higher timeframe) bar. Proceed to next higher TF bar, but keep same j (1M bar) { Buf_0[i]=result; //just some calculations i++; //go to next higher TF candle dt1=Time[i]; //search from date dt2=Time[i-1]-60; //to date result=0; //just some calculations } } // while return(0); }
total_1M_Bars=candles*Period(); // maximum M1 bars.
There can be missing bars on the M1 vs higher TF. There is Max Bars on Chart. BOGUS- Don't double post. You were already given the solution for this previously. Algorithm/Timeframes problem - MQL4 forum

Hi and thanks for your help.
this is not a double post since what i m asking its completely different with my previous post.
As i said in my first post what i m trying to do is no matter on which TF i am to find a way to check for a specific period time (eg 14 Period, 21 Period etc).
By period i mean how many bars to calculate back...that extern parameter that many indicator has like MAs, RSI etc. eg 14RSI, 21SMA etc... i do not mean the timeframe period
Also by the total_1M_Bars=candles*Period(); works fine for me. I do not care if there will be any missing bars cause i check for it later on in the
dt=iTime(Symbol(),PERIOD_M1, shift ); //get datetime of current shifted M1 candle if ( dt1 <= dt && dt <= dt2 ) // if datetime of M1 bar (dt) is between the desired dt1 and dt2 then...
Although thanks for noticing cause now that i m thinking off maybe this is the reason for some hangs i m still getting through weekends.
