Well, prior to the Norgate beta program, you were able to reference watchlists like this:
I would think you could make this work:
#include_once “Formulas\Norgate Data\Norgate Data Functions.afl”
InWatchList(NorgateIndexConstituentTimeSeries(“Dow Jones Industrial Average”);
But that doesn’t work. Anyone know if there is a way to accomplish this with the Norgate beta?
You need to ask Norgate support as
NorgateIndexConstituentTimeSeries is their plugin function.
@seaworthy It is probably worth checking with @NorgateData Richard Dale to see if the following code is correct. But I too have the NDU data feed and have put together this small afl to check for accurate prices and historically correct Index constituents.
I’ve used my own selected numbers for minimum Stock Price and volume for filters but obviously depending on your system or what you are trading you should insert your own preferred prices and volumes as filters.
I have run a couple of backtests and this seems to work but no promises as to it’s accuracy. If you check it too and it works it would be great to hear about it.
