A trader has to be patient and wait for the right signal to enter the market and by that you will be satisfied even if you lose the in that trade because you waited and got convinced it was the right time for you but if you are not patient you may jump in many times because of no direction. So waiting for the right time is a good trading skill and don't allow your emotion to always control you.

To BB you mentioned, it also have different time frame and you didn't mention the time you use. Bollinger band is an indicator that goes after the market so it is not reliable. Using RSI and MA that indicate overbought or oversold are still not certain for a reversal immediately but it only prepares you ahead that trend can change soon.
