is it possible to put a stop loss on a bought coin after you have bought it ? Just wondering because i am still learning and have only just come across stop loss. I use coinbase pro - is it possible on there?
I understand that you are imagining like stop-loss orders are something a special type of orders and we need any special arrangements for that. But in reality, stoploss orders are just similar to what we are usually doing to sell the coins but you need to put in advance so that your losses will be in expected (acceptable) limit rather than being unlimited losses.
You bought a coin, fine; then what you will do to take profits? You will sell higher prices than your buying prices, right? So, you will put sell order which is higher than your buying prices and this can be done with the help of usual order types. Because, you are going to put the order which is higher than the current market prices.
When we are selling higher than current prices then ordinary sell order is enough which is usually we do to book profits.
But, stoploss order is needed be put lower than current market prices hence we need to put with the help of stop-loss order type, which will not trigger until that price reaches.
If you put lower prices than current market prices to sell in normal order type then that will be executed at current price levels itself; which will not serve the purpose.
