The problem is that MetaTrader does not manage decimals or fractional percentages, they must always be percentages that have an exact value, example:
100 -> 30% remains a remainder of 10, this is the error. If it were 20%, 25%, 50% the division would always be exact.
Question, do these codes work? How could you add the option of Sell and Buy in the same code, as with a small window?
A thousand pardons for my English.
