the settings you have mentioned seem to be ok.
in 30 min chart, there is no need to see the ema. you can just see the stoch in 30 min and see whether it is in bullish phase or bearish phase. after that you can switch to 5 min chart for the actual trade after you confirm 5 min stoch and ema crossovers.
as mentioned by regardson, you need to pay 350 for subscription to get intraday live charts. icharts.in also provides a similar service i think.
before you go for subscription, you can paper trade this strategy on banknifty intra-day live data that investbulls provides for free and see the results. i think this strategy should work well with banknifty too.
