I know that lower margin and low leverage are also farther away from the liquidation price, so is it okay to set low margin and low leverage first to avoid losing if your strategy doesn't work, and then add if does the price follow your strategy? Is this also your strategy?
Leverage is the easiest way to get an account all blown off. Low leverage and low margin keeps your trading strategy in check. As a trader matter how good your strategy might appear it won't give you a profitable trade at all times. But with low leverage and low margin keeping it all in check it helps save trades both in losing and winning trades
Personally I have always thought that only a selected few should use leverage at all and the rest should simply avoid it as the risk that you lose it all raises exponentially the more leverage you use.
Since even a low amount of leverage like 3x and 4x can be more than enough to destroy your account relatively quickly, now some may argue that a stop loss can be more than enough to save them, but we know that when there is a high level of volatility in the market slippage can be enormous, so even with a stop loss your losses can be way higher than what you thought and be more than enough to erase almost all the profits you got during a bull market.
