Frequently Asked Questions

ta.cross() combines crossover and crossunder: source1 is strictly above now and was at or below previously, or strictly below now and was at or above previously. Equality on the current bar alone is not a cross.

ta.crossover() is true only when source1 crosses above source2. ta.crossunder() is true only when source1 crosses below source2. ta.cross() fires on either type of cross between the two series.

Use ta.crossover() or ta.crossunder() when you need directional logic (bullish vs bearish). Use ta.cross() when you only care that an intersection happened, not which way it went.
