Always put stop losses and take profit that is the real answer, the real enemy is your emotion. If you can control of yourself you can win that is why in trade there is a term called fear and greed. You fear when minus is coming to your PNL but sometimes we greed when our PNL is green.
If there is an option stop loss over liquidation the best option is always to choose stop loss
Fear and greed is definitely a good indicator, I have always seen it work perfectly so far. Stop loss is one that I would agree, but take profit isn't one that I would fully agree with. I can see why that would feel the same way, but I hope that it would not be all that same. In the sense that if you do stop loss, then you avoid losing money and that is all what we should achieve here, just not lose money as long as we do not lose money, we are doing fine.
On the other hand, if we could just "not make profit" that is fine, it is not the same thing, because take profit makes you try to take your profit as early as you can, but without it, you still could just use stop loss and avoid losing. And that way you can wait for it to grow further than your take profit number and make even more money.
