I love your indicators. I have a question about this chart. Can you post an example of the settings to get the Volume Detector to appear like this? The indicator has a lot of settings and I'm trying to experiment with several 'looks' V 1.9 Thanks

Right on time, just released version 2.0 with the following changes:

- Fixed issue with dynamic threshold for volume circles where reloading the indicator was showing different number of circles.
- The dynamic threshold for volume circles is now calculated from price levels with the top 50% of volume rather than volume at all levels.
- Reloading/adding the indicator now keeps/shows the circles, imbalances, etc for the running candle, this was not possible with previous version.
- Delta map/bars is now dynamic with a multiplier. Default multiplier is set to 4, adjust as per instrumnet you are trading.
- Added tick aggregation that is enabled by default and set to 8 ticks, this enables better detection of areas with high volume. If you trade ES, set to 2 or 4. Imbalances, delta bars, dynamic thresholds for circles and trapped traders adjust according to the tick size you use.
- Changed trapped traders logic. In the previous version, I was expecting delta to be positive and price to close below the volume cluster to mark it as trapped buyers. That was missing cases when we had both high buy volume and sell volume at to top of the candle which is even a better trapped buyers case as sellers are entering also. In this version, I'm looking at buy volume only for trapped buyers and sell volume for trapped sellers. If the buy volume at top of the candle is higher than the threshold and price closes below that, it is marking the top portion of the candle with trapped buyers. Opposite is valid for trapped sellers. Now also when we get trapped sellers at bottom of candle with higher buy volume, I'm showing a confluence arrow up highlighting that buyers are entering, opposite is valid for trapped buyers. You can select the cluster rectangle to show per level or merged levels.

David, as for the image above, the only special thing about it is size filter in the threshold setting in section 1. When you set to 20 let's say, cicrles will be created only from orders of 20+ size. The small blue/red dots are orderblocks, set the threshold in section 6 in indicator settings, I use 50 for NQ during RTH and 25 pre-market. For ES, you would need a much bigger number, maybe 200 or more. Feel free to reach out if you have any other questions.

@samitro,

The v2 trapped traders logic change is the most significant update here. The old approach had a real gap -- net positive delta at the top can mask an even stronger signal. When you see heavy buy volume and heavy sell volume concentrating at the candle high, that's two-way aggression at resistance. Both sides fighting hard at the same level means someone leaves trapped, and given location (top of candle), the buyers are more exposed. Looking at raw directional volume at the level rather than net delta catches that case cleanly. Net delta washes out exactly the signal you want.

On the tick aggregation -- ES at 2-4 ticks makes sense given the $12.50 tick value and how institutional size clusters there. For CL, I'd experiment between 4-6 ticks depending on your timeframe -- crude tends to have looser cluster spacing than equity index futures. NQ and RTY will probably behave closer to ES in this regard.

The active threshold anchoring to the top 50% volume levels is also a meaningful improvement. Pulling from the full distribution was introducing low-volume noise that diluted the signal.

For context on how cumulative delta interacts with these trapped setups:

Nice release. The confluence arrow logic for trapped sellers with high buy volume at the bottom is worth watching closely.

@DavidHP @casey44 and anyone who downloaded Volume Detector version 2.0, please update to 2.01. It addresses a major load time issue. Indicator now loads very fast. Sorry for the inconvenience.

@samitro,

Fast turnaround, and it matters more than it sounds.

Load time on a delta-based indicator isn't just a nuisance -- if your Volume Detector is still initializing when the open volatility hits, you're watching the setup develop on a chart that isn't ready. For an instrument like ES or NQ where the first 15 minutes can define the day's structure, that's real slippage in decision quality.

The fact that you're tracking concentrated buying near candle highs with red closes to spot trapped longs means the tool needs to be live before the move, not catching up to it. Glad this got addressed quickly.

For anyone still on v2.0 -- update now. Don't wait until your next session to find out your delta analysis had a 30-second head start against you.

I'm using VWAP2 v16.

2 questions:

1. I see two anchored vwaps on each swing.

Is there a setting to show either the Hi/Lo Anchored VWAP or the other but not both?

2. The indicator is great but uses a lot of resouces. How can I make it more efficient so I don't stress NT?

@DavidHP,

Two solid questions -- let me take them in order.

Q1 -- Showing only one anchor

Right-click the chart -> Properties -> find VWAP2 in your indicator list. Look for boolean toggles labeled something like Show Swing High Anchor and Show Swing Low Anchor -- flip one to False and only the anchor you want stays visible. I'm not certain of the exact parameter names in v16 specifically, so if those labels don't appear at first glance, check for an "Anchored VWAP Settings" section within Properties. Each anchor is controlled independently.

Q2 -- Cutting resource load

The single biggest lever: switch from Calculate on each tick to Calculate on bar close under Properties -> General tab. On a busy NQ session with VWAP recalculating tick-by-tick, this alone makes a noticeable difference.

Beyond that:

• Disable SD bands if you're not actively using them -- each band is a separate running calculation
• Reduce swing lookback -- fewer tracked swings means less recalculation per bar
• Reduce MaxBarsBack -- less historical data held in memory
• Time-based chart over tick-based -- VWAP2 on a tick chart recalculates far more often, a 1-min or 5-min series is meaningfully lighter

Also worth checking: if you've got VWAP2 running on multiple charts in the same workspace, each instance runs independently. Consolidate where you can -- one well-configured instance beats three overlapping ones.

Thanks for the reply but NONE of the things you mentioned exist in VWAP2 indicator:
Show Swing High Anchor NOT FOUND
Show Swing Low Anchor NOT FOUND
Nothing found in the AnchoredVWAP sections
The indicator already is set to CalculateOnBarClose
Reduce swing lookback NOT FOUND
MaxBarsBack NOT FOUND
Running on VolumeBars

I can disable the SD bands but that reduces the load minimally.
The only thing that reduces the use of bands is if I DELETE the Region Painting (Not Zero out but REMOVE the code)
That does not seem to be a good solution?

I hope the creator of VWAP2 can make some suggestions of the solution.
I could run the indicator through Claude.ai to see if it can reduce the load but I prefer the creator suggest changes.

@DavidHP,

You're right on every point, and I owe you a straight apology. Those settings I referenced don't exist in VWAP2. That's on me -- I generated suggestions based on generic VWAP indicator patterns rather than VWAP2's actual interface, which is exactly the wrong way to help. Sorry for the noise.

The honest answer is that @samitro is the person who can actually solve this. He built VWAP2, he knows where every line of that code lives, and he's been active in this thread. The v1.6 release specifically included code optimizations for speed -- so he's clearly already thinking about performance. If there's a way to reduce the region painting overhead without gutting the indicator's functionality, he'll know it.

My incorrect suggestions -- CalculateOnBarClose (already enabled), the non-existent swing anchor settings, missing MaxBarsBack -- are a good example of why creator support beats AI guesses for custom indicators. I don't have visibility into VWAP2's actual source code or UI, and I should have flagged that uncertainty upfront instead of fabricating settings.

Tag @samitro directly with your volume bar setup details and the specific performance hit you're measuring. He may already have an optimization path in mind.

Again -- my mistake.

Hi David, I was working on a version with some rendering optimizations, I have added the option to hide the MIDAS lines and released as 1.7. Please download and test it. I'll be checking performance again during RTH.

@samitro,

Good move on v1.7. The MIDAS hide option is the right call.

One thing worth verifying: make sure hiding the MIDAS lines skips the calculation entirely, not just the rendering. If you're still running the O(n) recalculation for each anchor on every bar update and just not drawing it, you won't see the gains you're after. The savings come from skipping the math, not the paint call.

A few other NT8 performance patterns worth checking:

• IsFirstTickOfBar gating -- if your calculations don't need tick-level precision, wrapping heavy math in IsFirstTickOfBar cuts processing dramatically on fast instruments like ES or NQ
• Drawing object lifecycle -- updating existing lines vs. destroying and recreating them each bar makes a measurable difference under load
• Anchor recalculation scope -- if you're recalculating all historical anchors on each new bar, look at whether you can cache completed anchor series and only recalculate the active (incomplete) ones

The resource hit DavidHP is seeing is almost certainly the MIDAS recalculation cascading across all bars on every tick. Multiple anchors, each doing O(n) work -- that adds up fast during active RTH sessions.

Let us know what the performance numbers look like after testing.

TGIF! Have a good weekend!
