breakout Pre_Market high low

[shih90]

Is anyone know the LABEL showing that when bell open morning stock runs up down and break either side premarket high/low ?
Thank you for your research and help!!!

 

[ganeshinbarajan]

your words are too vague.

what do these this mean?
1. bell open morning stock ? all stocks open in the morning
2. runs up down ? how far up? how far down? based on what ? is this even important ?

--------------------------

here is a study that,
. finds the highest and lowest levels during pre market,
. draws lines at those levels during normal hours
. draws an arrow if price crosses above the high line or below the low line

This indicator is showing premarket high/low only for spy. Its not showing for any other stocks. Can you please check it?

Hi @halcyonguy. In looking at charts using your script I note that the pre-market plots are pulling data from the after-hours session of the day before, rather than from the pre-market session starting at 0400 hrs of the current day.

An example would be ticker TSLA from today (April 11, 2023). The PM low being plotted ($184.06) is the low from yesterday's after-hours session rather than the low from today's PM session ($184.50).

I am not a coder so don't have a suggested fix, but thought I would share this as an FYI. Keep well.

@halcyonguy
After using the Premarket High Low indicator, I realized that the indicator is pulling the data from whichever level meets the high or low criteria during either afterhours or premarket price action.
For Pre Market High example $AMZN: the premarket high of 4/14 shows a high of 107.94, which is the high of the candlewick from the 4/13 afterhours price action.
For Pre Market Low example, $NVDA: the premarket low of 4/17 shows a low of 212.29, which is the low of the candle wick from the 4/16 afterhours price action.
I hope this helps in determining how the code discriminates between afterhours and premarket, for example these two lines of code from the DailyOpen TOS script, to only show data from the opening bell candle:

input aggregationPeriod = AggregationPeriod.DAY;
input showOnlyLastPeriod = yes;

This may not help, but it's part of my researching other TOS indicator code to see if I can find code to isolate premarket from afterhours times.
Thank you, cmf

Hi. Is it possible to do for premarket? and is it possible to place this script in the watchlist after the selection of stocks in the premarket, so that the stock that has broken through the premarket price would be highlighted? I ask for help!

i'm sorry for responding so late, i'm sometimes terrible at replying.
i see you 2 probably aren't around, but will still reply.

@shih90
here is an updated version

@DMacTrades
there is nothing to fix. i took the original request to be any time that isn't normal trading hours, hours before normal trading hours AND hours after them.
after hours, pre market,... these terms could be interpretted differently or as the same period, unless specific times are mentioned.

@LivingWithInterest
..read data from pre market and after hours,.. yes. i lumped them together in my previous version.
you wrote a lot of words, without defining WHAT time period defines what you want. although providing examples are usually good, i'm not going to type in symbols , and go look up data from some date, and try to interpret what you want.
just say , read data from 4am to 9:30. (or whatever the correct EST times are)

how can I turn this code into a scan filter?
