In my opinion, Tradestation stinks as a charting package......Ensign has this tool and so may others built in.
That'll merely give you the high of the current bar. It's fairly easy to do though - take into account the time frame of the chart, and the current time. Then get the highest high and the lowest low since open using the lowest and highest functions.
This will plot the intraday high and low of the current day on a 1 minute chart. Just change 0830 to whatever time zone you are in for the open. If you use a longer interval than 1 minute, divide MinSinceOpen by the appropriate interval in the plot statement (Ex. Plot1(Highest(High, MinSinceOpen/5), "High"); for a 5 minute chart, etc.) {Start code} Vars: MinSinceOpen(0), StartMin(0); If Time = 0830 then StartMin = TimeToMinutes(0830); MinSinceOpen = TimeToMinutes(Time) - StartMin; Plot1(Highest(High, MinSinceOpen), "High"); Plot2(Lowest(Low, MinSinceOpen), "Low"); {End code} Make sure you plot the indicator as points rather than a line so that each new high or low is not connected together.
Sure, you can take the easy way out if you want....LOL Thanks for the tip...not sure why I have to make things so hard sometimes.
Brahahaha... Plot1... Plot1... and it only plots the High and Low of the bar... Rather use: Plot1(HighD(0), "High of Day"); Plot2(LowD(0), "Low of Day"); LOL
