Features
See who's really in control
Price tells you where the market went. Volume Delta tells you who pushed it there — the aggressive buyers or the aggressive sellers.
Buyers vs sellers, instantly
Delta above zero means more buying pressure; below zero means more selling. The color-coded read tells you who's winning at a glance.
Spot institutional prints
Large delta prints reveal when big players step in — the kind of surges that push price hard and often start the next move.
Volume-based support & resistance
Visualizes where trading activity concentrates, helping you pinpoint the levels of real buying or selling interest.
Tick-by-tick, non-lagging
Delta is calculated from completed transactions tick by tick, so what you see is what traded — no smoothing, no lag, no repainting.
Any market & timeframe
Order flow is universal — the indicator works across futures, forex, stocks and crypto, on whatever timeframe you trade.
How it works
Read the tape, not just the price
Every trade happens at the bid or the ask. Volume Delta adds up the aggressive buying (at the ask) and aggressive selling (at the bid) and shows the net — the delta. A positive delta means buyers are lifting offers; a negative one means sellers are hitting bids.
Watch for big delta prints at key levels, divergences between delta and price, and shifts from buyer to seller control. It's the same order-flow read the pros use to see who's really driving the market.
A large positive delta print signals aggressive institutional buying.

What is Volume Delta?
Volume Delta is the difference between volume traded at the ask (aggressive buying) and volume traded at the bid (aggressive selling). A positive delta means buyers were more aggressive; a negative delta means sellers were. It shows the order flow behind each bar.
How does it help me spot institutional activity?
Large delta prints stand out on the chart. When you see an unusually big positive or negative delta at a level, it often signals institutional buying or selling stepping in — the kind of activity that can push price hard and kick off the next move.
Which platform and markets does it support?
It's a native NinjaScript indicator for NinjaTrader 8. It needs a data feed with bid/ask volume, and works across futures, forex, stocks and crypto on any timeframe.
Can I automate a strategy around it?
This is the visual indicator. If you'd like Volume Delta traded for you automatically, the Order Flow Strategy is the fully automated bot built on the same order-flow read.
Are there recurring fees?
No. It's a one-time license with free updates for the lifetime of your license — no monthly or yearly renewals.
