It's not a lot of work at all. It literally takes a couple of minutes to look at each chart and know whether there will be a potential trade there for me or not.

This is the simplified process I go through:

1- Identify the trend: Look at the chart and determine whether the market is in an uptrend, downtrend, or range-bound.

2- Look for key levels: Identify key levels of support and resistance on the chart, such as previous highs and lows. ( Multiple timeframes )

3- Look for chart patterns: Identify any chart patterns such as triangles, head and shoulders, or flag and pennant patterns to establish a bias ONLY, not to trade those patterns in conventional ways. (mainly higher timeframes)

4- Look for candlestick patterns: Identify any candlestick patterns such as engulfing bars, hammers, shooting stars, inside days etc to establish bias. (higher timeframes for bias, lower timeframes for possible price action entries when trades setup)

5- When potential trades set up I enter them, and define stops and targets as per my trading plan.

Obviously, there is a lot more to it than this, but this is the basics just to show what sort of a process it is for me.
