getTodayOHLC.efs

[gdargento]

Anyone know how to change the getTodayOHLC.efs to exclude premarket (include only 8:30 - 15:16 CST)? I'd like to draw H/L for regular market hours only.

Thanks

Time Templates

You should be able to create and apply a time template for your chart that sets the time interval for the data. Right click on your chart and choose Time Templates -Edit.

Hello gdargento,

werosen's suggestion is part of the solution, but there is more to it. unfortunately, the formula will not do what you need because it get's its data from the daily chart. You will need a new formula that collects the data you're after from the current chart interval the formula is running on, which will use the specified start and end times of your custom time template to filter out the pre-market data.

What the formula will need to do is establish some global variables such as nHigh, nLow and nOpen. Look for the first bar of each day and reset the global variables using that first bar of that day's data.

if (getDay(0) != getDay(-1)) {  // we have a new day
    nHigh = high(0);  // set to current bar's high
    nLow = low(0);  // set to current bar's low
    nOpen = open(0); // set to current bar's open
} else {  // still the same day as the last bar
    nHigh = Math.max(nHigh, high(0));  // set to new bars high if greater
    nLow = Math.min(nLow, low(0));  // set to new bars low if lower
    // leave nOpen alone until the next day is found
}
