Prior day and pre-market high low

31 Jan 2023

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.

Nota Keluaran

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.

Nota Keluaran

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.
