Hi,

I have a couple of esignal studies (vwap and regression lines) and a custom
indicator that was written for me for esignal. I've recently transferred to
thinkorswim and want to know if it was possible (and where/who) to convert an
esignal study to thinkorswim. I have the formula (source code). Esignal uses
javascript, i believe.

Please advise.

Thank you.

Here is what a google search returned for me

tos has regression lines and vwap already.

If you have something custom then yes it will need to be converted.
I would ask Prospectus or thinkscripter if they could help you.
They have their own websites. check them out.

gonna mess around with the VWAP when I get home. Didn't know they had that as an indicator...
