it's helpful to use both 1- and 2-minute candlestick charts together. experimenting w/other timeframes is also useful, eg 1/2/5/15s for confirmations.
another tip: I like using a 2-day 2-min chart, along with a 1/2 day 1-min chart for a closeup look. I set 1/2 day 1-min chart track time from premkt, eg starting 8am or so, going til around 11:30am.
I set the 2-day 2-min chart to also start premkt, going til end of market day each day. this helps you see the prev day OHLC (open/high/low/close) as well as intraday support/resistance and fibonacci levels, to help w/entry triggers for open range breakouts and breakdowns.
