i was always told to buy in the red, but if that's true is there a certain % when it's in the red i should buy. For example on binance 24h Chg% xxx coin is -18.74% is that too low? or should you buy in the -3 to -5% range?
percentages doesn't matter on their own, it is important to see what coin you are seeing these percentages for and when.
for example a 20% drop in bitcoin warrants a buy without thinking twice because there will be a recovery after it even though it might continue dropping after that recovery. but a 20% is a shitcoin is not a buy signal because it will get dumped more and there is a good chance for it.
and the timing is also important. there are times when you see a drop after a rise which is the correction of that rise but the bull market has not ended, that is the time to buy but sometimes it is a bear market and the price is dropping constantly, and there is a time when the pumped altcoin is getting dumped hard. you should buy in that case at all because you will get dumped on.
it it take time but you will get the hang of different scenarios and will learn what to do in each case.
