SAR set to open prices only

RE: Reply to post 'SAR set to open prices only'

David,

This formula changes the outcome, once establish
within given time interval. For exapmple, if you get
the buy signal on One Hour chart, it could go back
and change to sell again within one hour.

var study = new ParabolicStudy(0.02, 0.02, 0.2);
function preMain() {
setPriceStudy(true);
setPlotType(PLOTTYPE_SQUAREWAVE);
setDefaultBarThickness(4);
setDefaultBarFgColor(Color.red, 0);
}

function main(){
if(getBarState==BARSTATE_NEWBAR);
return study.getValue(ParabolicStudy.STOP);
}

Before I was using:
setComputeOnClose(); instead of if(getBarState==BARSTATE_NEWBAR)
and computeonclose didn't change, except it was drawn
on the previous bar's close price. I am just looking for the calculations
based on the screen - Line/Tick charts set to "Open" so the oscillators
don't change (sort of what you see is what you get until next
time interval's open). It looks like it still follows the very last tick,
not the first tick of the interval.

Would appreciate if you can help me.
Peter

Does anybody know how to setup
Offset to Parabolic SAR formula???

Hello peterkl,

[JayF]

You can offset any built-in study by using the getValue function and by specifying an offset factor. For example,

return study.getValue(ParabolicStudy.STOP,-10);

Attached is an example based on Alex's new built-in study forumlas.

Thanks JayF,

One question: is there a way to setup
computing prices based on new open rather
than last close prices?
For example Instead of:
setcomputeOnClose(); I would like to have a study
that calculate only open prices, so the
charts and signals don't change once
established on the screen.
Thank You
Regards
Peter

Hello peterkl,

setComputeOnClose as defined in the Help Center is "... callable from preMain() only and, when used, will force the current EFS study to only update when a new bar arrives (as opposed to updating as each new tick comes in)."

This is different then computing a study from the closing prices (but I can see where the confusion came into play.) I'm not aware of any easy method to implement the Parabolic SAR calculation on the Open. If someone is aware of such a way, please post a reply.

Thanks.
