If a trader knows some math then it's good for traders, I think every trader knows some simple maths they can calculate pip values, on the forex market if a trader knows some economics then it's very good to understand fundamental news. In loving the way you open this thread. I am not very good at Mathematics and I am definitely not a mathematician but still I can do it well on Forex so that means that Forex does not require mathematics in depth the only involvement of mathematics is in calculations.
