Multivariate Calculus Robot is designed to analyze and work on every available Currency Pair. Calculus Robot Implements algorithms that govern their work. These algorithms detect some sort of "Waves" in the Forex Market. In Robot's Default Configuration, the Average Trade length is twelve hours. Take Profit delta is equal to the Stop Loss delta in every trade. That kind of trade operation is symmetrical, which means that if the BUY operation was a loss and then reversed it, the SELL operation with properly modified values would be profitable. When the Results of the Robot's work are to be analyzed after at least two months, it appears that the Robot switches time intervals, which is Losing Money to time intervals, which is Making Money. Those intervals appear to be a few days or even weeks in length. The standard technical analysis used on robot results can be used to detect when those intervals begin and end. When done, Robots work at runtime and can be properly modified Lot Size.
