Volume delta is one of the best trading indicators you can use when trading order flow. It gives you an instant snapshot of the buying and selling pressure in a market.
After reading this post you will understand how volume delta provides a critical edge by allowing you to spot potential large reversals in the market. You will also learn how to use the cumulative delta indicator to manage your trading positions.
What is Volume Delta?
Volume Delta is the difference between buying and selling power. Volume Delta is calculated by taking the difference of the volume that traded at the offer price and the volume that traded at the bid price.
If delta is greater than 0 you have more buying than selling pressure. If delta is less than 0, you have more selling than buying pressure.
We use delta to understand the relationship between buying or selling pressure and price.
Let’s imagine a price bar that reached the low for the day and delta was negative but the bar closed higher than it opened.
In simple terms we can describe this as:
- Price made a new low
- The bar closed higher
- Delta demonstrated more selling than buying pressure
Without looking at the chart below, would you be more inclined to do, go Long or Short?
If you said long you were correct. More on this later…
Volume delta is a key metric to understand when making trading decisions based on volume and order flow. However, on its own it can be too much information to interpret quickly when trading in a volatile market.
As a trader, I like to view things visually at a glance… Introducing Cumulative Volume Delta.
Cumulative Volume Delta
Cumulative volume delta takes the delta values for every bar and successively adds them together to visually provide a graph as seen above.
While volume delta is great for comparing delta bar to bar, cumulative volume delta is useful when determining buying or selling pressure at different price levels such as swing highs or lows.
Let’s do a quick recap on swing highs and swing lows.
A swing high (SH) forms when the high reached on a security is higher than price action around it. Once price moves above a prior swing high and begins to retrace a new swing high is formed.
A swing low (SL) forms when the low reached on a security is lower than price action around it. Once price moves below a prior swing low and begins to retrace a new swing low is formed.
When price is making higher highs followed by higher lows a market is considered to be in an uptrend.
When price is making lower lows followed by lower highs a market is considered to be in a downtrend.
When evaluating delta it’s extremely beneficial to compare delta values at swing lows or swing highs to determine the amount of selling or buying pressure and how the market is reacting.
The true power delta is revealed when we use it to determine the market’s reaction to powerful buying or selling. We want to see if the market has reacted as we would expect or not.
In the above example you will notice every time price breaks a swing low, delta does as well.
This makes sense as it takes selling pressure to break a swing low or buying pressure to break a swing high.
BUT….what’s occurring when this isn’t the case and we have divergence between price and delta?
Trading Exhaustion with Delta
Exhaustion: When less buyers are willing to buy at new highs or when less sellers are willing to sell at new lows, represented by delta.
On the above chart notice how price breaks out to new highs but Delta doesn’t follow through.
When this occurs the buyers are said to be “Exhausted” as they aren’t interested in buying at the new highs.
You can see above how the exhausted buyers began to liquidate their positions driving price down.
Let’s take a look at another exhaustion setup.
In this example price is now making new lows but delta wasn’t able to. The sellers are now said to be “Exhausted” as they aren’t interested in selling at these new lows.
The end result was the exhausted sellers began liquidating their positions driving price up.
Trading Absorption with Delta
Absorption: When aggressive buyers are unable to take price to new highs or when aggressive sellers are unable to take price to new lows. The aggressive buying or selling pressure is being “Absorbed”.
In the above example delta is making new lows but price isn’t following through. Even though there’s aggressive selling pressure, that pressure is being “Absorbed” by the buyers.
Resulting in a rally as seen above.
In the next example, delta is making new highs but price doesn’t follow through. Can you guess what’s occurring here?
The buying pressure was “Absorbed” by the sellers resulting in a sell off.
Cumulative Delta & Trade Management
Delta not only will help you spot major reversals, but it can be used to help manage your open trades as well. When in a position, whether long or short, you want to see high correlation between delta and price.
If you’re long while price is breaking new highs you want to see delta breaking highs as well. If buyer’s aren’t interested in buying at the new highs, represented by delta not breaking highs, the probability of a reversal increases.
If you’re short while price is breaking new lows you want to see delta breaking lows as well. If sellers aren’t interested in selling at the new lows, represented by delta not breaking lows, the probability of a reversal increases.
When in a position always be on the look out for exhaustion and absorption signaling a potential of a reversal.
