Hello, so I've been in the forex market (currency trading and exchanges) for quite some time, I've done reasonably well, however I was curious as to how perhaps calculus and other mathematical methods could benefit me. Basically, I am a day trader...I wanted to know if there is a way to predict probabilities in the market based on the previous day and trends. I was wondering if differentiation the charts would tell me the rate at which I can expect the currencies to change the following day. Would this be a good method? thoughts please.
