How to Read an Order Book Histogram

The Order Book is essentially a visual tool that shows the current trading activities in the Forex market. This includes information on active trades, pending orders, and Stop orders. Each of these trades is aggregated and shown at various price levels in the form of a histogram.

To fully cover all the trades, we divide them into two groups, which form two separate histograms: the left one and the right one. In the following picture, you can see the various orders that make up the snapshot of the Order Book.

Order Book Snapshots Quadrants


For simpler understanding, we’ve divided the histogram into quadrants.

  1. Sell Limit, Take Profit (Buy);
  2. Buy Stop, Stop Loss (Sell);
  3. Sell Stop, Stop Loss (Buy);
  4. Buy Limit, Take Profit (Sell);
  5. Profit Buyers;
  6. Loss Buyers;
  7. Loss Sellers;
  8. Profit Buyers.

The green line marked with a price on the OrderBook snapshot shows the current market price at the time the snapshot was taken.

Ratio bars

Beneath the histograms, you can find ratio bars that provide additional information.

Ratio bars in Order Book

  1. Percentage ratio between pending buy and sell orders.
  2. Percentage ratio between buy and sell positions that are still in the market.
  3. Ratio of Profit vs Losing trades.

These bars dynamically change as you navigate through the snapshots.


The histograms come with extra labels that offer additional information.

Order Book Labels

GR (Gravity) – the price level where the highest stop loss accumulation is located. It’s known that the price gravitates toward it.

SR (Support/Resistance) – highest accumulation of limit orders which may act like a support/resistance level. Should have much more volume than the Stop orders accumulation on the other side to be valid.

MV (Middle Volume) – For both histograms, there’s a price level indicated where half of the orders are above and half are below this level.

OB (Overbought) – Indicates the price level where over 70% of buyers would be in profit, suggesting that the asset might be in an overbought condition.

OS (Oversold) – Indicates the price level where over 70% of sellers would be in profit, suggesting that the asset might be in an oversold condition.

Understanding the Order Book Dynamics

The order book’s dynamics reveal how trading volumes change over time.

Order Book Dynamics

When you move your cursor over the chart in the OrderBook snapshots tool, you’ll see changes:

  • In the left order book. For instance, at some price levels, the number of trades (volume) increases, while at others, it decreases or stays the same. This helps you understand which price levels are attracting more interest and where the price might move next.
  • In the right order book, pay attention to how quickly Buy and Sell trades are completed at different levels. Sometimes, Buy trades close faster than Sell trades, and other times it’s the opposite.

A key piece of information comes from observing how the price first moves up or down and then returns to where it started. By comparing the order books before and after these price changes, you can often figure out the reason behind these movements.

This kind of analysis helps in understanding market trends and trader behaviors at different price points.
