Hi. I'd like to ask for some advice: I want to use a month or two of fluctuations in the EUR/USD index (or another major one) to determine what numbers to use as triggers to automate trading. If, for instance, over the course of a month an increase of X in the index was followed by an increase of Y before it was followed by a decrease of Z 80% of the time, then I will automate the platform to buy when X happens and sell when Y or Z happens. Will this work? How many percent should I expect to make in a month this way?

Thanks! I appreciate your help!
