Trapped Volume & Orderblock Scalper

Pair of ACSIL strategies for Sierra Chart that detect real-time trapped volume imbalances in the orderbook and use them to drive an intraday scalping system around orderblocks.

Project overview

Two custom Sierra Chart studies work as a pair: a real-time trapped-volume detector and an orderblock-based auto-trading strategy built on its signals. They read volume-at-price data to find stacked bid/ask imbalances, mark where aggressive traders are trapped, and automatically generate and manage trades around those structures.

Trapped volume engine

  • Reads Sierra Chart's volume-at-price data per price level and computes bid/ask imbalance ratios, with separate thresholds for NY and Asia sessions.
  • Identifies "stacked" imbalances over multiple price levels and flags likely trapped buyers/sellers.
  • Draws real-time overlays and markers to visualize trapped zones on the footprint chart.

Orderblock scalper (auto trading)

  • Wraps the trapped-volume signals into an ACSIL auto-trading strategy that runs tick-by-tick.
  • Configurable momentum/reversal candle filters, minimum volume, and imbalance position within the bar; separate enable flags for long/short.
  • Uses Sierra's trading APIs for real-time order routing, position tracking, and PnL-aware exits.
