Scale order

What it does: splits a large order into multiple limit orders across different price levels to form a ladder.

Typical use: staged entries/exits, mean-reversion plans, or building a position without a single fill point.

Key parameters: price range (start/end), number of levels, sizing per level (fixed or weighted), and side.

Tradeoff: can improve average price and reduce impact, but may only partially fill if price does not reach all levels.

Example: place a buy scale from 59,800 to 59,000 across 5 levels; as price dips, limits fill progressively, averaging the entry.
