Overview of Graph Indicators

In Surveyor, the Indicators window can be used to show Liquidity Curves, Spread, and Position, which are detailed below.

Liquidity Curves

A liquidity curve is the volume of shares quoted that is visible to the public in the top 10 tiers on either side of the order book.

There are a few important distinctions made with different colors:

Dark green = buy volume of public order book

Dark red = sell volume of public order book

Light green = buy volume of individual firm or accounts

Light red = sell volume of individual firm or accounts

Position Indicators

The position curve represents the position of the firm as a whole or of an individual account.

Spread Indicators

The spread, also called the bid-ask spread, is the difference between the highest price that a buyer is willing to pay and the lowest price that a seller is willing to accept.
