Stack Signal vs. Typical order-flow add-ons
Most order-flow add-ons start from the same L2 feed. The differences that matter are whether the series is filtered, whether both platforms match, and whether features are gated by plan.
Stack Signal
The raw stream, both platforms
No smoothing, no feature tiers, provably identical numbers on Bookmap and NinjaTrader 8.
- Exact Passive + Aggressive decomposition
- Same engine on Bookmap and NT8
- Every plan is the whole product
- Warming-up and stale states instead of fake plots
Typical order-flow add-ons
Often filtered, often gated
Many tools average, threshold, or hide signals behind a higher tier. Two platform ports can silently diverge.
- Smoothing and look-ahead are common
- Feature tiers split the same indicator
- Cross-platform parity is rarely proven
- Dead feeds can look like a quiet book
