NinjaTrader’s Order Flow + premium tool set includes powerful chart studies to assist with order flow, volume and market depth analysis. The Cumulative Delta indicator helps order flow traders identify and monitor buying and selling pressure.
What is Cumulative Delta?
Delta refers to the net difference between buying and selling volume at each price level. Cumulative Delta builds upon this concept by recording a cumulative tally of these differences in buying vs selling volume.
Passive vs Aggressive Orders
For traders using Cumulative Delta, limit orders are considered passive while market orders are considered aggressive. In other words, buying at the ask or selling at the bid are considered aggressive since these orders will fill immediately. This implies a sense of urgency in the market.
With that in mind, the Cumulative Delta calculation uses the following formula:
- Market Buy Orders – Market Sell Orders = Delta
When this result is a positive value, the buyers are seen as more aggressive and vice versa. Cumulative Delta keeps a running tally which displays a comprehensive historical and real-time view of order flow delta activity.
Using the Cumulative Delta Indicator
The Cumulative Delta indicator plots as candlesticks in a panel below the price at time information. One of the main uses of Cumulative Delta is to confirm or deny market trends.
In the example shown above, while the charted price data may suggest a bullish trend, the Cumulative Delta indicator featured in the bottom panel does not confirm this bias.
Two Views of Cumulative Delta
There are two ways to plot the Cumulative Delta indicator, Session and Bar:
- Session displays the delta accumulating over the course of a trading session with the closing price of the previous bar carried over to the open of the following bar. The example above shows a session display.
- Bar displays the delta value per bar with no continuity. Therefore, it appears more as a bar graph with the value of the delta plotted as a positive (green) or negative (red) bar.
The bar display of the Cumulative Delta indicator is pictured below with each bar within the Cumulative Delta corresponding to the price bar directly above it. This display is helpful for identifying reversals or sudden changes in Order Flow activity.
