alert when price bar crossing specific price line

james272 2021.09.13 12:16

Hi!

i found a indicator script on the net which suit for me .

this indicator draw and alert when crossing specific above and below line.

But one lack of function is when break out line it alert but there is no limit bar .

i want to set 5 bars so if i set 5 bars i want to receive alert in 5 bars only if over 5 bar like 6 , 7 ...

i just want to skip and ignore this alert.

i checked this script and found Close[0] is ok when check current price crossing above or below line but if i limit to 5 bars then it make some difficult for me.

i thought to use iTime function .

for instance if i want 5 bar limits then i thought i can make it with

iTime(_Symbol, 0, 0) + timeoffset > LastTime

so if timeframe is 5min and 5 bars is 25min so i set timeoffset as 1500

but it not working.

i tested with different value but not working .

If I have understood correctly, this is the changes you want. See the attachment.

You have an input to limit the number of times an alert happens and then resets after some time (as input).

if you want alert after(?) 5 bars (your explanation is really not very clear) - can see the signature of iClose

double  iClose(
   string           symbol,          // _Symbol
   int              timeframe,       // _Period
   int              shift            // shift at certain bars quantity  
   );

? perhaps you need shift to adjust

LastPrice = iClose(NULL, 0, 6); // 1+5 because when closed the bar is aleady closed & new bar opened, the closed bar is having index [1] + 5 = 6th bar from the right side - break-even occured
