AB-BidAsk-Ratio: Bid/Ask ratio indicator for NinjaTrader

AB-BidAsk-Ratio is a set of FREE indicators that highlight bars where the Bid/Ask ratio exceeds a user-defined threshold level. Oftentimes bars with higher than normal Ask:Bid ratios indicate buying pressure/levels and bars with higher than normal Bid:Ask ratios indicate selling pressure/levels. Using these indicators, you can quickly see such bars on your charts.


  • Plots histogram showing the difference between Bid/Ask volumes for each bar.

    • Positive values indicate more ASK volume (BUYING interest).

    • Negative values indicate more BID volume (SELLING interest).

  • Bars with a ratio exceeding the threshold value are highlighted in the chosen colour whereas other bars are grey.

  • All values exposed as public plots to allow integration with other indicators/strategies/alerts.

  • Threshold value and colours are customizable.


  • Draw a marker above bars with a ASK:BID ratio exceeding the configured threshold value. Draw a marker below bars with a BID:ASK ratio exceeding the configured threshold value.

  • This is a purely visual indicator at the moment.

  • Useful if you don't want another panel on your screen (i.e. AB-BidAsk-Histogram) and only want to quickly see bars that exceed your configured threshold.

  • Threshold values, marker colours and marker size are customizable.
