It's always important for us to follow our trading strategy as planned to avoid losses, in every trade there's a target profit so any one who doesn't follow or have a trading strategy won't know when to take profits, he might even end up getting a loss, have had similar experience I was trading binance futures with any trading strategy,I was +$14 in PNL, I didn't know when to take profit instead of cashing out the $14, I got rekt after a day my account got liquidated, so knowing when to take profits off the market is important.
