Here is my Simple Leverage Scalper strategy, utilizing BBands and RSI.
Preferred timeframes are between 1min and 5min, but you can do whatever.
Notice that the strategy uses Heikin-Ashi prices instead of Close Prices. This is because of the continuous candles; they work much better with RSI as they generate more breakouts.
To make this strategy even better, you could add a trend indicator to distinguish when to allow LONG entries and when SHORT entries. At the moment the strategy does both, but longs might not work well on bearish markets and vice versa.
