Hi,
You can use “High” or “Highest” not only for price, but also for an indicator.
For example:
xDIplus = DIplus[14](Close)
If you want to determine the “Highest” value of this indicator, you can use:
HighestDIplus = Highest[period](xDIplus)
So, you replace the price (Close) with “xDIplus”.
For the “period”, you can set a custom value.
For instance, on a 5-minute chart, you could use a period of 288 (since 288 x 5 minutes = 1 trading day).
Your formula would then look like this:
xDIplus = DIplus[14](Close)
xDIminus = DIminus[14](Close)
DIdiff = abs(xDIplus – xDIminus)
HighestDIdiff = Highest[288](DIdiff)
CrossOver = DIdiff crosses over HighestDIdiff[1]
