BM Cumulative Delta

CATEGORY: Indicator · For NinjaTrader 8 · Chart Style with Colored Bars Based on Executed Delta

HOW IT WORKS: BMChart is an indicator that calculates the executed delta on each bar—the buying pressure versus selling pressure, measured using real ask/bid buy data—and colors the body and wick of each candlestick according to that pressure, not whether the bar went up or down. An upward move without aggressive buyers looks visually different from an upward move with strong buying delta.

The color intensity is self-calibrating: it recalculates over a moving window of bars (200 by default), taking the configurable percentile of the absolute delta (85 by default) as the "maximum color" point. This means that the same indicator works equally well on a low-volume instrument as on a high-volume one, without the user having to manually adjust any thresholds. The color is applied in 8 intensity levels per side (bullish/bearish) to create a smooth gradient.

It uses the same delta calculation engine as BMOrderFlowEdge, and it displays this information without requiring a NinjaTrader Order Flow+ license or Tick Replay—both modules also work with historical data.

WHO IS IT FOR: Visual traders who want to read order flow directly in the form of chart bars, without a separate panel or indicator to consult, and who don't want to pay for the additional Order Flow+ license to access this information.

TECHNICAL REQUIREMENTS: NinjaTrader 8. Any instrument with available tick data.
