i'm not sure that the loss is only due to an improper trading platform, because in trading a TA is part of the other main factors that make a loss from trading, because even though we trade on an inappropriate trading platform but the TA we do is very good then i'm sure it will still make a profit
I believe this, exchanges with high volumes will probably move faster than exchanges with low volumes. and the problem of profit or loss depends on the trader doing the research and transactions therein. therefore when doing research you must carefully to see the price action that occurs.
