Effective relay forms must meet:

1. Appear in a clear trend;

2. Supported by convergence or channel structure;

3. There is a clear breakout direction, accompanied by trading volume or candlestick momentum;

4. There are clear structural stop-loss points to rely on.

In terms of operation, it should revolve around the three points of 'breakout means entry, structure means stop-loss, and form height means take profit', rejecting vague and feel-based attempts to bet on reversals.

Lastly, and most importantly, do not try to capture every form. Being proficient in one or two types of forms can lead to substantial profits!
