I see that the biggest mistake that the most of traders do it is the trade with huge lots and high risk to profit with no plan or money management so this is the reason of the loss to a large portion of traders. So i think that we need to control on this and dependably maintain a strategic distance from the trade with high risk and with huge parts in light of the fact that the trade with plan is the best thing that dependably lead us to the achievement. At least we should follow 1:1 risk and reward ratio because a survey shows that most traders are right in more than 50% times.
