That's a dumb move that will hurt any trader involving in such kinds of trades, the only time I jump into trade like this is when I enter the market and I realize that the entire market has serious dump like the similar one that occurred on the day Els Salvador announced Bitcoin as legal tender, that kind of situation aren't meant trader to be doing support and resistance, I buy all the red until I'm become out of fiat and sells back the moment market stabilize and the profits are always good.
Scalping is one kind of trading that requires your smartness to know when to take the available profit and close your trade
Scalping is good way to make cool bucks without doing much but I find it hard to leave my trade more than 4 hours, I don't get comfortable except the situation I highlighted above, I.e when the market has seriously dump, it will be hard to make an instant profits except if there is high volatility for fast moves. This has help me stay out of market making U turn against my trades, I go into market, makes some profit and then I'm out safely, no one gets hurt.
