How do Order Book and Book Pressure help analyse liquidity in FYERS Smart Charts?

Order Book and Book Pressure are features within Liquidity Lens on FYERS Smart Charts that help you understand the distribution of resting buy and sell orders. Order Book visualises cumulative market depth across price levels, while Book Pressure summarises key information about Bid and Ask liquidity, including order quantities, imbalance and spread.

Order Book

The Order Book displays cumulative Bid (buy) and Ask (sell) quantities across different price levels.

It includes three reference points:

  • B (Best Bid): The highest price buyers are willing to pay.
  • A (Best Ask): The lowest price sellers are willing to accept.
  • Mid: The midpoint between the Best Bid and Best Ask prices.

The Bid and Ask curves show how resting quantities accumulate as you move away from the current market price.

This helps you identify whether liquidity is concentrated near the current price or distributed across a wider range of price levels.


Book Pressure

Book Pressure summarises resting liquidity on the Bid and Ask sides, making it easier to compare the quantities available in the order book.

It displays the following information:

  • Imbalance: Shows which side has more resting liquidity across the top 50 price levels.
  • Top 50: Shows resting quantities across the top 50 price levels.
  • Full Book: Shows quantities across the entire available order book.
  • Average Order Size: Displays the average order size on the Bid and Ask sides.
  • Spread: Shows the difference between the Best Bid and Best Ask prices.

Order Book vs. Book Pressure

Order BookBook Pressure
Visualises cumulative Bid and Ask quantities across price levels.Summarises resting liquidity using quantities, imbalance, average order size and spread.
Helps identify where liquidity is concentrated or distributed.Helps compare the balance of resting liquidity between the Bid and Ask sides.

Using both features together helps you understand how liquidity is distributed across price levels and how resting buy and sell quantities compare.

What if...

ScenarioSolution
More resting quantity on the Bid side than the Ask sideThis indicates that the displayed order book contains more resting buy quantity than sell quantity within the measured levels. It does not guarantee upward price movement.
Different liquidity balances in Top 50 and Full BookLiquidity may be distributed differently near the current market price compared with the wider available order book. Comparing both views helps you identify these differences.

Note: Order Book and Book Pressure provide information about resting orders, which may be modified, executed or cancelled. The displayed liquidity does not guarantee future price movements.
