If you find that your favoured instrument to trade calls for larger charts instead of the default 2:1/3:1 - 5:1 - 8:2, just change the chart settings when you put the strategy on the Precision Chart, and you're all set. (Note, though, that your new settings will not be saved when you close the chart.) Trading the GC, TF or CL? Feel free to experiment with settings like these (All SiProRenko settings): 3:1, 5:1, 8:2, 12:3, 16:4
Just make sure you create and attach an appropriate ATM to the strategy on the new charts where the initial stop is beyond the entry bar!
