Displaying Tick Data and Change Flags in a Trading Indicator

Summary

This brief indicator description explains how tick events can be collected from a trading terminal into an array and shown on screen. Each displayed tick can carry a flag identifying the type of event: a change to bid, ask, last traded price, or volume, or an indication that the tick resulted from a buy or sell trade. These flags help distinguish what changed in the stream and provide a basic view of intraday market activity.

The description is limited to the indicator’s data-display behavior. It does not explain how to infer aggressor direction beyond the supplied buy and sell flags, how ticks are filtered or stored, or how to use the output in a trading strategy. It gives no market, backtest, or execution results, so the material is primarily a concise reference for interpreting tick events rather than evidence of a trading edge.

Key ideas

• The indicator collects terminal tick events into an array and displays them.
• Tick flags identify changes in bid, ask, last price, or volume.
• Buy and sell flags identify ticks marked as resulting from trades on either side.
• The description does not provide a strategy or evidence that tick flags predict returns.
