Library "ema_stoploss_lib"

This library derives stop-loss levels from a dynamic list of EMA lengths. It computes each EMA internally (so dynamic lengths are allowed), keeps strict side filtering (long: only EMAs below the source; short: only EMAs above), sorts by distance to the source, and returns the n-th nearest value plus the original index of that EMA length.

get_stop_loss(index)

Initializes (once) a default length list:
21, 50, 100, 200, 250, 500, 750, 1000.

Returns: [sl_buy, sl_sell, nearest_buy_idx, nearest_sell_idx]

sl_buy / sl_sell: selected EMA values

nearest_buy_idx / nearest_sell_idx: 0-based indices in the original lensArr

Parameters & Notes

Index (input in the example; default 2) is 0-based:
0 = nearest, 1 = second nearest, 2 = third, etc.

If there aren’t enough EMAs on the requested side, the value becomes na (plot will skip that bar).

Strict filtering means no fallback to the opposite side.

Performance:

EMA updates are O(n) per bar (n = number of lengths).

Sorting is O(k²) (k = candidates on the chosen side) — negligible for small lists.
