Better Dynamic Liquidity HeatMap Profile Indicator: Bins

Written by Dominic Walsh · Published 29 Jul 2026 · Last updated 18 Sep 2026

The better dynamic liquidity heatmap profile indicator answers where trading happened, not when. It splits the recent range into horizontal bins and totals the volume that traded inside each one. The busiest bin gets marked.

This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

A look at the plots

Filled rectangles pin to the right edge, one per price bin.

Bar length shows volume at that price, and colour runs cool to hot.

`InpPocColor` `clrAqua` marks the busiest bin with a line and a price tag.

A corner panel summarises the profile, and no plot buffers exist.

What happens on each bar

Bins first

The high and low across `InpLookback` `240` bars set the span. `InpBins` `30` divides that span into equal price slices. Every slice then collects volume.

Spreading beats bucketing

`InpSpreadRange` `true` shares each bar’s volume across every bin its own range touched. Switch it off and the whole bar lands in the bin holding its typical price. Spreading gives a smoother, fairer profile.

Length and colour both encode volume

The fullest bin gets `InpMaxWidth` `50` bars of length, and the rest scale against it. Colour runs from dark blue for thin liquidity to yellow for heavy. So the shape reads at a glance.

How to interpret it

A long hot bar marks a price the market kept returning to.

Thin bins mark prices that traded through quickly.

The point of control is the single busiest price in the window.

`InpBinGapPct` `10` leaves a gap between bins so they read as separate rows.

This build ships no alerts at all. There is no master switch, no popup, no phone route, no mail and no sound. It is a drawing tool that recomputes once per new bar, so anything you want to act on has to be watched by eye.

Matching it to your chart

A profile needs enough bars to fill its bins. EURUSD H1 is the reference chart, where `InpLookback` `240` covers about ten days. On M5 the same count is under a day. Higher timeframes give a broader, slower map.

Where care is needed

Forex tick volume counts price updates rather than contracts, and brokers differ.

The profile recomputes once per bar, so it never reflects the forming candle.

Thirty bins across a wide range makes each slice coarse.

FAQ

What does InpSpreadRange true change?

It shares each bar’s volume across every bin the bar’s high to low range covered. Switching it off drops the whole bar into one bin at its typical price, which makes the profile blockier and less faithful to wide bars.

How does InpBins 30 affect the reading?

It sets how finely the range gets sliced. More bins give a detailed profile that needs a taller chart to read. Fewer bins give broad zones. Thirty is a compromise that suits most screens.

What does the InpPocColor marker show?

The point of control, meaning the single price bin that accumulated the most volume in the window. It is the price the market spent most effort at, which is why it gets its own line and tag.

Does InpLookback 240 include the current bar?

Yes, but the whole profile only recomputes when a new bar opens. So the forming candle contributes nothing until it closes, and the map you see always describes completed bars.

Are results guaranteed?

No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Better Dynamic Liquidity HeatMap Profile Indicator as one input. Always backtest before trading live.
