Cross

[[cross]] is a conditional block that compares two numeric expressions, reference and comparison, evaluated on every candle. Both fields can contain a series, a calculation, or simply a fixed numeric value.

It triggers when a cross is detected in either direction.

Bullish cross:

• ${\text{reference}}_t>{\text{comparison}}_t$
• ${\text{reference}}_{t-1}\le {\text{comparison}}_{t-1}$

Bearish cross:

• ${\text{reference}}_t<{\text{comparison}}_t$
• ${\text{reference}}_{t-1}\ge {\text{comparison}}_{t-1}$

When either condition is met, control jumps to the block specified by next_block_id. The block compares expressions evaluated on every candle and covers both bullish and bearish crosses.

Block declaration#

A strategy can contain multiple [[cross]] blocks.

Example#

[[cross]]
id            = "ma_cross"
reference     = "fast_ma"
comparison    = "slow_ma"
next_block_id = "next_block"

Block parameters#

This block does not produce any output; it simply controls the execution flow when a crossing happens.
