plot Futures pair difference on NT chart

[sukhob]

I am trying to plot Futures Pairs on my chart. For example, Notional Difference = The Notional Value of Market "A" minus the Notional Value of Market "B". How would I accomplish this in NT7 and NT8?
Thanks,

Hello sukhob,

To compare two instruments or two sets of data and then plot them you would need to make a multi instrument indicator. You can find some examples and information about making multi instrument scripts in the following links:

nt8

After adding the secondary series and a plot, you could do various equations with the data and plot the result:

double value = Closes[0][0] - Closes[1][0];

This would subtract the secondary series from the primary.

I look forward to being of further assistance.
