You are right, but every trader should always take note that they should just use the amount they can really afford to trade, this will give the best mindset and a rest of mind. If more amount is used, if the market has gone in the wrong direction, it may lead to the trader making mistakes which are not perfect at all. Trading is risky, but can be profitable if the right decisions are taken, but some traders just do it the other way like others and continue to lose.
Of course, you have to use an amount of money they can afford to trade and also can afford to lose. Do not impose an amount that exceeds the maximum capacity that can be traded. Everything must be managed properly so that it can provide profits and trade according to the initial strategy. Trading is indeed risky, but behind the risk, there are benefits that can be taken. No trade is perfect, every trader will also experience losses several times before making a profit.
