    Does anyone have a simple indicator that shows the pre market high and low as lines on a given chart?  Would be grateful for the code.  Thanks

    What times do you want to use for the pre-market and what time frame…?

    And ideally the the PML and PMH lines would then show until the start of the next premarket.  Alternatively, unbroken continuous lines for the currect PMH and PML would suffice.  I would like these to appear on the chart irrespective of the chosen timeframe.  Thanks

    Hi,

    When you work with times then the time frame must be adjusted accordingly, for example the end time in the US pre market is 14:30:00 so you can only use a time frame of 30 minutes or lower, moreover the highest time frame (here 30 minutes) must be a multiple of the lowest time frame (for example you can use ten minutes because 3×10=30 but not eleven minutes because 3×11<>30)

    This one is for the “European Markets”… 

    //European Markets

TimeFrame(30 minutes, UpdateOnClose)

If OpenTime=073000 then
xHighest=Highest[16](High)
xLowest=Lowest[16](Low)
EndIf

Return xHighest as "High" Coloured("Green"), xLowest as "Low" Coloured("Red")

    Thanks for the code.  The indicators appears in a separate window.  Is it possible to have these lines drawn on the actual chart?

    Hi,

    Use “op koers = on graph” and the other is “nieuw paneel=new panel” you have to choose and in this case “On Graph”…
