I hope the code for the candlesticks in the ThinkorSwim platform will at least get you headed in the right direction. There are some sites online that you can pay to join that might be able to help you. Or, once you get something roughly written, you can email the thinkscript people at TOS. I haven't done that but, that's what they have told me when I inquired about help.
It takes me a lot of time but, eventually I figure out how to write the code to do most of the things I want on my charts. I have posted a lot of code in the intro box that I wrote and/or pieced together from other code I've seen. There is some code Spdpro shared as well there. I haven't written anything like you want. However, when I was coming up the learning curve, I posted a lot of information and links in the iBox. Perhaps you will find something there that is useful to you.
Best of luck and good trading.
