thank you for being so polite. You are welcome to take any study and modify it to your benefit. The only thing that we would ask of you is to leave the original citation on top of the script so that everyone knows where it came from. Put your name and date underneath the original citation.
The advice you have been given regarding how to learn think script are all good. Some learn from reading tlc.thinkorswim.com while others learn from dissecting scripts that they have come across. I personally have learned the most from the Universe of Thinkscript in the tutorial section, as posted above.
A little background, as I know it to be, is that thinkscript is its own unique language that has its roots in Java. It was created as a new language by a number of Russian Programmers. There are many things that would be nice to have in this language but as I understand it, Arrays is the biggest one that hinders us from creating a more complex script.
Take your time learning how to be a trader/investor. Find one area that interests you and become proficient at it, whether it is daytrading, swing trading, position trading, or trend trading. There is a great big world out there that is easy to get lost in.
