custom calculated chart

[pipsalottle]

Hi,

I would like to chart the difference between two instruments (like spread) but with a calculation included.

for example Crude oil 04-15 - (minus) (crude oil 05-15 * 2)

so that is Crude oil april 2015, minus crude oil may 2015 times 2.

hope this makes sense.

Thanks

Hello,

It would be possible to accomplish this with a bit of custom programming in NinjaScript. You could add a secondary data series within the code, then perform calculations involving both data series.

If you would like to go the custom programming route, I'll be more than happy to point you in the right direction as to how this can be done.

Please let me know if I can assist further.

Thanks Dave, i'll have a crack at it.. i'm assuming i'll be building an indicator?

Hello,

That's correct. You will need to use Add() to add a secondary data series, and Closes[int barSeriesIndex][int barsAgo] to access the close prices of bars on either data series. You can find more about Add() and Closes at the links below:

Please let me know if I can assist further.
