Don't use a stop-loss. Stop-loss means to sell after the price drops. Don't traders realize that a stop-loss is literally buy high, sell low?
Stop-loss is generally used by traders for loss protection. They mistakenly believe that a stop-loss will get them out quickly if there is a crash. It will not.
In case you weren't aware, some flash crashes are not accidents. You can make money in a flash crash by picking up coins sold due to margin calls and stop-losses.
The bolded statements above contradict yourself. I think I get your point, but it's mis-directed. It's not the stop-loss that's used incorrectly when set to (literally) protect against a loss. It's the fact that cryptocurrency exchanges have no legal requirement to execute your stop-loss trade within seconds of your price floor being penetrated.
Stop-loss orders are as effective as the company you're asking to "pull the trigger" on the sale for on your behalf. A price alert would be more useful in the Bitcoin world.
To the OP, it seems like you're doing a series of 3 trades in a row, there's no intent to hold for some defined period of time in between the trades, yes? If that's the case you gotta just push on through and complete your three step trade.
