Different traders follow different policies, styles, strategies. I trade by following the stop loss policy. I always take three or four entries and give 15 pips of take profit and 45 pips stop loss. I think profit will be given a third stop loss. Because I see the market conditions. and even with a stop loss, the trader's account still gets a margin call if the trader uses a large lot size. What's good is a combination of stop loss and money management. If you combine two margin calls away from the trader. Traders use 10% of accounts to open positions and set a 50 pip good stop loss. If trading losses, then only 5% of capital is a loss. If you can trade in this way it will not be easy to get a margin call.
