Let’s put it this way. There are some strategies that can harvest the returns derived from illiquidity, liquidity provisioning, and variants of the momentum factor intraday. Those strategies require expert knowledge of market structure, liquidity, and flow to be successful. No one running those strategies uses a chart and patterns.
If you did a study on price returns you would find that the majority of +1std moves in daily prices are due to catalysts — either once information is revealed or positioning prior to that. So in order to trade those successfully the hard work is in analyzing the catalyst and what you expect the impact to be on price. (View -> expressed financially in terms of rev/costs/or fcf -> estimated impact to price -> compare to price reaction and volume = trading signal).
Daily fluctuations within 1std are really just noise as the price is driven by the limit order book and at the market volumes. Unless you have an edge on measuring flow and the limit order book (which is not data represented in charts and patterns) you won’t be able to successfully position. If you’re just a hobbyist then obviously do what you want to do, but if you’re trying to generate alpha and compete, then I’d suggest reconsidering your approach.
