# Technical Studies Reference

The study displays both the Bid and Ask Price for the latest trade at each bar in the chart. We denote the Bid Price and Ask Price at Index $$t$$ as $$(P_{bid})_t$$ and $$(P_{ask})_t$$, respectively. This study only works with Intraday charts.

For this study to have the necessary data it requires, it is necessary to set Sierra Chart to a Tick by Tick Data Configuration.

Depending upon the source of historical Intraday data for the particular Data or Trading service you are using, historical Bid and Ask prices data may not always be available. Data received and stored in real-time will always have Bid and Ask data available.

The Bid and Ask Prices study uses the Bid and Ask prices at the time of the latest trade in each bar. These Bid and Ask prices only update when there is a trade. However, at the last bar in the chart the latest Bid and Ask prices are used.

1. Select Chart >> Chart Settings.
2. Set the Use Number of Days to Load >> Days to Load setting to a small number like 1 or 2.
3. Set the chart bars to 1 Number of Trades Per Bar by setting Intraday Chart Bar Period >> Bar Period Type to Number of Trades Per Bar. In the box below enter 1. For complete details, refer to Time Period Per Bar/ Amount of Data Per Bar.
4. Press OK.
5. Add the Bid & Ask Prices study to the chart. For instructions, refer to Adding/Modifying Chart Studies.
6. The data from the study can be overlaid to other charts by using the Study/Price Overlay study.
