Recommend any indicator for trading the currency pairs?
Try the 50 MA
Depends what you want the indicator to do.
If you want it to give you an entry signal, forget it. As I said recently, that would be like buying bread because the price of flour just went down.
There are other questions important to a strategy and if the price chart alone cannot answer these, an indicator can help. But make sure the extra information is really necessary and that this is the right indicator to give you the answer.
But you must not forget that it is very important to choose the right indicator. Indeed, in fact much depends on this, too.
maybe best just start looking at charts and becoming familiar with candlesticks at different time frames maybe alot of people who start are yearning for it to be more interesting than it is
candlestick s best indicators
As long as you understand the indicator any would do , dont use to many as will only cloud your screen and judgement , 1 or 2 max RSI is a good place to start
