It is quite common to see people getting liquidated or facing a margin call and then feeling sad,
or suffering significant losses and crying while writing "what should I do 😭"
Do they not understand risk management, risk-reward ratio, and how to determine order size and stop loss?
These three things must be understood first, determine where the stop loss is, and determine "how many dollars you are willing to lose when the stop loss is hit", this will later determine what size you should enter,
for example, if you want to lose $1 when the stop loss is triggered, and the stop loss price is a certain distance from the entry price, then you determine what size to enter so that when the stop loss is hit you will only lose $1.
No matter how far your stop loss point is, if you understand this, you will still lose only 1$ .
Then occasionally monitor your position, if you are already in floating profit, move the stop loss to your entry price to achieve zero risk trading.
Or more easily, you can use trailing to close positions that are currently in floating profit.
Hope this helps
