Not all coins are traded with same candle amplitude, some are similar some are more profitable for trading.
No, you are getting this wrong. A large amplitude does mean a large percentage change but that does not mean that the coin is worth putting money in. First thing you need is research on that asset, just by seeing a shitcoin pump to 400% in a few hours does not mean you should money in it, rather you should stay away from it.
See, these rises in price in an asset often are due to pump and dump. Identifying them is difficult, however you can evaluate some risk factors for them. If the coin is a shitcoin/abandonware/ghosted team etc, you can be sure some bagholder is pumping the price just to sell it.
Without browsing each coin pair, do you have a method how to detect such coins that are traded as high amplitude candles?
Percentage change per day and keeping tabs on the common names in that seems the best apporach to this, however know what I have already said and be cautious before putting your money in them.
Remember, the dream of flipping penny coins quickly to get rich is a common one, reciprocally uncommon are those who actually profit from it.
