shot time frame series in long time frame chart problem

[gp]

I've run into this issue a few times before and ignored it but now I have to solve it. Due to recent volatility, I've had to add a short section of 1 minute bar trade stop code onto a 3000+ line efs running on a 5 minute chart and ended up withe quite a bit of null data on both dynamic and static time templates. Here is some proof of concept code:

function preMain() {
setPriceStudy(true)
}

//Globals
xStudy1min=null;
xStudy5min=null;

// Run this on a 5 minute chart (I'm using dynamic chart)
function main() {

if(xStudy1min==null) xStudy1min=close(inv(1));
if(xStudy5min==null) xStudy5min=close();

for (var i=0;i<5;i++){
debugPrintln(xStudy5min.getValue(0) +" "+xStudy1min.getValue(-i));
}
debugPrintln("********************");

}

On historic bars I am assuming that "main" only runs once per 5 minute bar so I try to specifically query the 5 individual minutes of the 1 minute series. The print-out consists of several hundred null values for the 1 minute series before I get a couple dozen prints at the end that are OK. Looks like:

A lot of this
********************
1254.5 null
1254.5 null
1254.5 null
1254.5 null
1254.5 null
********************
1198.75 null
1198.75 null
1198.75 null
1198.75 null
1198.75 null
********************

And then some of this at the very end (top):
********************
1160 1160
1160 1159.75
1160 1159.25
1160 1158.25
1160 1160
********************



I am assuming that what happens is that historical bars are only fetching the 5 minute series and the 1 minute series only exists for bars that were drawn when real - time data was being plotted (that's why a longer time series in a shorter time chart always works ok)???

I must be missing something. (Being lazy I'd rather not recode/debug a few thousand lines to make them 5 minute dependant so I can plot them on a 1 minute chart; I also thought of passing globals between charts but that would prevent back-test)

Hello GP,

You're mostly correct. There isn't the same number of days of data loaded for the lower time frame. Try adding setIntervalsBackfill(true) to preMain.

Thanks for your rapid response. Tried the setIntervalsBackfill(true) but didn't seem to make any difference.

The only other reference I could find in the form was your response in:

http://forum.esignal.com/showthread.php?threadid=18253

that suggested to me that the shorter intervals somehow get loaded in.

I guess I've got to to bite the bullet and redo the 5 min chart code (that I should have added a lot of inv(n) to in the first place.)

I'd love to learn a little of the details on how/when various series get loaded when in historical mode.

Wow. When I closed e-signal restarted and redid the chart the backfill worked!!!! Thanks, you saved me days of work.

You're most welcome. For future reference, instead of restarting the application you could also just remove and then reapply the formula to the chart.
