Prior day and pre-market high low

This indicator displays the:
- Prior day high
- Prior day low
- Pre-market high
- Pre-market low
as a coloured line across the entire session for each individual session on an intraday chart.

For the extended session, this indicator marks the prior day and pre-market high low for each individual session starting at the pre-market and ending in the post-market, a feature not available on other indicators.

This indicator automatically marks out the levels for the prior day and pre-market high low for each individual session, allowing the user to observe how the price action behaves around the prior day and pre-market high low.

Note:
In this script, request.security() used with lookahead = barmerge.lookahead_on to fetch prices without offsetting the series by [1] for the extended session does not access future data. This is because for extended session, request.security() sees the start of the session to be at the start of the regular session and ends at the end of the pre-market, when in reality the session starts at the start of the pre-market and ends at the end of the post-market.

Hence in each extended session when the line is first drawn in the pre-market, request.security() returns the value of the prior day high/low, and not future data.

Note di rilascio

Added individual line style (solid, dotted, dashed etc.) setting for prior day high, prior day low, pre-market high, and pre-market low price levels.

This allows users to use different line styles for different price levels, such as having solid lines for prior day highs and lows, and having dotted lines for pre-market highs and lows.

In the previous version all 4 price levels use the same line style base on the user's selection.

Note di rilascio

Added the option to show the most recent price level value on the price axis to allow users to be able to see the value of the price level at a glance.

Added the option to toggle the display for each individual price level and price axis label.

Included additional options to customise each individual line colour, thickness, and style.

Changed the colour for prior day low from red to magenta so that it does not clash with the default red used in the charts.

Note di rilascio

Added the option to customise the visibility of the value on the price axis according to the timeframe.

Note di rilascio

Added the option to customise the appearance of the price level to display one of the following:
* Individual level for each day

Note di rilascio

Added option to allow users to create an alert for price crossing/closing above the pre-market high or below the pre-market low.

Note that users will need to manually create the alert by doing the following:
1. Select their desired security and timeframe on the chart

3. Under Condition, in the first drop-down, navigate to this indicator. In the second drop-down, select the desired alert
4. Under Trigger, if users would like to have the alert on bar close, select "Once Per Bar Close". Else if users would like to have the alert once condition is triggered, do not select "Once Per Bar Close".
5. Set Expiration, Alert name, and Message as desired

Note di rilascio

Edit: typo

Note di rilascio

Updated script to more accurately reflect prior day OHLC and current open, specifically to account for prices that the chart does not consider as regular session prices when viewing Extended Trading Hours, e.g. prices between 0930-0959 on the 1 hour timeframe.

However, this limitation still applies to pre-market high and low. E.g. on the 1 hour timeframe, if the ticker reaches a new high between 0930-0959, pre-market high value will reflect this high.
