Yes, 5 mn, On NY time session. You can use normal candlesticks, preferred Qrenko. On Ninjatrader, it's supposed to be better, so basically run it an create templates. Better not to take trades then have losing trades that kills the progress. Also, don't trust the strategy tester, you must run the strategy and test it everyday, of course no trading if you have news at 2 PM NY session too. Follow the rules, for great results.
PS: Create one sim account just for it, don't run other strategies on it, when on live market, to see for yourself.
