We can not take extreme risks anyway. Because it's more important to stay safe than to make big money in a short time. We have to use good money management always. Larger volumes can only be used later when the market is stable and at a certain position of the chart. and it's really great to double the lot and the double gain but we just have to be very careful in trading based on the increase of the lot because with more lots we can end up losing our account if we do not have enough equity left in account all day
