I suppose strategies for scalping are created taking into account high-volatility periods, as despite all prejudices that such periods are characcterized by high risks, scalpers benefit from that. I'm speaking about wise scalpers of course, who know how to catch the price's wave.
In any other case, if you are an intermediate scalper and you are afraid of roller-coasters, especially trading with leverage, then it's better to wait until the market calms down, or to choose another time period for trading. Scalpers usually trade when assets are very liquid, like during sessions overlaps, for example.
