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.

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.

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.

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 2. Go to the Create Alert dialog 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".

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.

Added a setting to adjust the label offset from last bar for each price level to address the issue of labels overlapping.
Added an option to include the price within the label text.
This is a fantastic indicator, love the clean labels and it's really helped with morning trades. Two ideas if you are open: 1) have it so

This is a great script. Been using it and helps a ton to see prior levels from a session. Is there anyway to be able to add prior Day Close, prior Day Open and Daily Open?

@fernandough, I can work on that. Could you elaborate more on the difference between "prior day open" and "daily open" that you require?
fernandough

@nkwdesmond, prior day open - the previous day's opening price. daily open - the opening price for the current session.

I love this indicator now I don't have to manually set my pre/post market lines. Can this code be used on TOS?

@Harlemknight124, I do not use TOS, so I do not know if that is possible.

Love this indicator. but for some reason premarket high low no longer work, I only able to display prior high, low, open and close but not pre-market.

@bqdang, Are you looking at regular trading hours? The limitation with trading view is that the script cannot calculate pre-market prices when regular trading hours is selected.
