@l-andorrà Not quite familiar with it

My bot is designed to enter after the formation of a fractal/swing structure.

For a fractal-up, the SL should be at the price of the very next higher fractal-up to the left.
For a fractal-down, the SL should be at the price of the very next lower fractal-down to the left.

SL is same timeframe as entry.

See below for example: the green line is the entry, and the red is the stoploss.

How can I implement something like this?
