Like my experience, it is a mistake when you see a failure and then you see a trade, if you get a continuous profit that can not be imagined because some cases we approximate close but most of the time not serious. It's not a miser for labial trade and for me, I never give up, no one should stop trading. just pause for a few days and analyze your mistakes you have in your transaction. Usually, tons size is just a problem for merchants. try to avoid large ton sizes. if you are a beginner, then choose a demo and follow the step by step procedure to induce expertise.
