Double Stochastic Multi-Timeframe

I personalized a double stochastic oscillator.

HOW IS IT USED ?
Everyone should adapt the parameters to its way of trading.
First you must have a confirmation of the trend.
In positive trend, a double stochastic > 20 can be used t enter long.
In negative trend, a double stochastic < 80 can be used t enter long.
Of course this is only one possibility that everyone should adapt.

I added the possibility to add on the chart a 2nd timeframe for confirmation.

If you found this script useful, a tip is always welcome... :)
