We do not use Grid or Martingale.

No, we don't use GRID/Martingale. The sequence of trades can be opened in a controlled risk manner by use of algebra, R = L[T∑n - X(∑n ² - ∑n)] the sequence and series part of algebra. However, we must know the direction first. And, we need wholesome analysis for the direction.

In the sequence formula mentioned above, R is risk (the amount which we put on risk), L is initial lot size, T = total price range in which we are going to open positions, n is number of positions, X is difference between price level of one and next position in the sequence.
