Look at this huge wick down on the daily time frame back in the 2017 bull run. Don't think that this can't happen now - it absolutely can. These flash crashes we see every week are a smaller version of this. You always have to be on your toes and make sure you are being diligent as far as following the rules. Always use pretty tight stop losses that follow you up into profit. Always take profits off the table when your trade is in profit. You can lose it all in a matter of minutes, it's not worth the risk.
Most importantly, don't leverage trade, and if you insist on doing it anyway, don't ever take your eyes off it unless it's in profit and you have a stop loss set in profit. When I tried leverage trading and leaving it over night, 9 times out of 10 my stop loss got hit. If you aren't in profit, you are losing money every single time that happens. Preserve your capital!
