Still testing. Gimme a little more time. I need to get @Hypoluxa ’s opinion also before posting.

So this morning i looked at /ES for the first time to monitor this. /ES at 9:00EST was $3859....so the GANN target was $3859.52 and then $3873 would be next. I did this to see if SPX would do that - make sense so far? well at 9:45 SPX hit $3873. Maybe a coincidence, but I'm def going to start testing this for GANN on /ES at 9:00 for SPX after opening.
 
Is there a script .. to get the GANN at pre-defined times ( say 6 AM PST, 7AM PST, 10AM PST, 12PM PST).


That'll be good visualization to begin with ... thoughts.

TIA

whats ur opinion on barbados indication? @Hypoluxa
 
I have this setup now
Buy at / above: 3937.56 Targets: 3951.28 - 3967.01 - 3982.77 - 3998.56
Stoploss : 3921.89
Sell at / below: 3921.89 Targets: 3908.2 - 3892.58 - 3877 - 3861.44
Stoploss : 3937.56

So trying to understand what you said. You are using the /ES price at 9.00EST If /ES is at 3960 at 9.00EST, SPX should be about 10 points higher or at 3970. So do you then put the SPX price of 3970 into the GANN calculator?

Hello @bhaskar_madugula can you please share the code for this strategy? It seems like MACD_BB but I just like to see how strategy is working. Thank you very much.
 
Here is a GANN square of 9 indicator I put together based on the spreadsheet @Hypoluxa posted a few months back. It updates at RTH open, 30 minutes after open, 90 minutes after open, and then once finally at after hours start. Looks to work well on various futures and stocks with varying start times.

@bigboss ..thanks for sharing your code.
Couple of requests, I tried to do it myself but was unable to as there is no reference of isupdatetime in the plots.

1. Can we have the labels related to the time. For ex: "RTH Buy Above: xxx.xx", "30min Buy Above. xxx.xx", "90 min Buy Above: xxx.xx"
2. Can this be used in a scanner to check if the price is above the plot line (5m aggregation) ?

Thanks!

Thanks

I updated post 114 with version 1.1, which adds in labels for Buy Above and Sell Below. They'll always show the current buy above/sell below price. If it is after hours and the lines are set not to show outside of trading hours, then the labels won't display either.

The scan syntax you would use would look like this, if you saved the script as "GANN9":

Code: 
close crosses above GANN9()."BuyAbove" within 5 bars

Obviously you can sub out for crossing below SellBelow, or crossing below BuyAbove if looking for a reversal, etc.

Thanks @bigboss, I too was able to add the labels for the current above/below, but was not able to get it for the other times.. thought that would be easy to do.

Cheers
 
When I add the latest GANN9 my candlesticks are really small. I changed it to the left axis and that seems to work. Will the indicator work correctly if I change it to the left axis?

Uncheck "Fit Study" on Price Axis settings, you will be all set after that.
