How can I create a spread of a spread?

[eMan]

I am relatively new to eSignal, and I was hoping someone could help me.

Presently, I have a multi-symbol chart comprising 2 spreads. I would now like to create a spread of these two spreads. This could be either in the form of a 3rd line on the chart, or as an "indicator" in another panel on the chart. Can this be done? If so, how?

Any help would be much appreciated.

Regards,

This would be best done with an EFS. For instance,

function main(sym1, sym2, sym3, sym4) {

return ((sym1 - sym2) - (sym3 - sym4));

}

I would suggest creating a more robust program by using Function Parameters, null checks and such, but the above snippet should give you the general idea, though.
