Add EMA into that and you are basically done already, most others are totally useless.
That might not be suitable for everyone knowing that they have their preferences with regards to what indicators they are going to use on it. It's always going to be the part where you could put so many indicators but they are just clouding your judgment. It's still best to stick to what you know, like what you said, yours is EMA, and stick to that. It's better that way.
I do not like Bollinger Band all that much because it just moves the post too much, it shows one thing and if it stays like that for a day suddenly what was insane yesterday becomes expected today according to BB and that is not something I really like in TA because I want some stability of my predictions.
You do know that BB's are based on MA's as well. It's in conjunction with a certain value of MA and there's just a ± of deviation from it. Everything is being looked upon though.
MACD and RSI is very nice as well, I have used them in a trading bot before and it did worked not so bad, especially when buying it is definitely catching right before it hits bottom, selling is quite difficult in any indicator at all times.
I believe too that entry is more important than the sell because as long as you have a %gain in your trades, it's still better than 0.
