What is thinkScript®?

thinkScript® is a built-in programming language that gives you the capability of creating your own analysis tools such as studies, strategies, watchlist columns, etc. In thinkScript®, you decide which kind of data to analyze with which methods. Functions present in this programming language are capable of retrieving both market and fiscal data and provide you with numerous techniques to process it. You are even able to combine many technical indicators in one by referencing them in your code or just using functions that represent the most popular studies such as simple or exponential moving average.
