Stacked Imbalance

Several consecutive levels where one side overwhelms the opposite one, left as lines extending forward.

What it measures

An imbalance is a price level where one side of the market traded much more than the opposite level: the buys at one price against the sells at the price above, or the other way around. When several consecutive levels show an imbalance in the same direction, that’s a stacked imbalance.

This indicator looks for them inside each candle and marks the price of every matching level with a line to the right. It doesn’t draw cells or clusters: only the lines over the price.

The default Stacked Imbalance on a 1-minute ES chart: ice lines for buy imbalances and pink ones for sell imbalances, each running until price touches it again.

How it’s calculated

Inside each candle, Forge compares the volume of each level with that of the adjacent level, diagonally:

  • Buy imbalance: the buys (ask) at one level against the sells (bid) at the level above.
  • Sell imbalance: the sells (bid) at one level against the buys (ask) at the level below.

there is an imbalance if own side ≥ ratio ÷ 100 × opposite side

The ratio is a percentage: 300 % means one side is three times the opposite one. In addition, the level must add up to at least the imbalance volume you set. When as many consecutive levels as the imbalance range specifies (3 by default) chain together, it counts as stacked and each of those levels leaves its line, not just one per group.

If the opposite side is zero, Forge takes it as 1 and almost any volume comes out as an imbalance. With Ignore zero values on, if there is nothing opposite there is no imbalance.

How to read it

  • Ice line: a stacked buy imbalance, at the level’s price.
  • Pink line: a stacked sell imbalance.
  • Until touched: by default, the line continues to the right until the candle whose range contains that price, where it’s cut off. A line that reaches the right edge is a level that price hasn’t touched again yet.
  • With a fixed duration: without Line until touched, each line lasts the number of candles you specify (the origin candle plus that many more), whether or not price touches it.

The lines mark what happened on the chart: where one side dominated several consecutive levels. They are not recommendations.

Stacked imbalances

On by default
What it marks
A horizontal line at the price of each level that is part of a group of consecutive imbalances: green if it’s a buy imbalance, red if it’s a sell imbalance. It lasts until price touches it again, or for the number of candles you choose.
Alert
It doesn’t alert: you see it on the chart.
Turned on with
Always on; what counts as stacked is set with «Imbalance ratio (%)», «Imbalance range» and «Imbalance volume», in Settings.

Adding it to the chart

In the chart bar, Indicators ▾ › More Indicators…. You’ll find it in the Volume / Order Flow category. It’s drawn over the price, on the chart’s own candles. How to add and adjust an indicator is in Indicators.

Imbalance ratio (%)300 %How many times one side must exceed the opposite one, as a percentage. From 100 to 2,000, in steps of 10.
Imbalance range3Consecutive levels needed for it to count as stacked. From 1 to 20.
