If you have the right broker and the right strategy for scalping, you can do pretty well.
You asked for an indicator. Let me post you some pictures.
To get the info as where this indicator can be found you have to email me at

The yellow dots represent "support area"
The purple dots represent "resistance area
The red dots represent "sell signal" and they are also used to indicate where stop should be (usually few pips above the reddot)
The blue dots represent "buy signal" and they are also used to indicate where stop should be (usually few pips below the last blue dot)
You sell when red dots are close to the purple dots (meaning: you sell at a solid resistance point)
You buy at the yellow line if the dots are blue (you are buying at the support level)
I don't know if there is anything easier then this for scalping or for getting 10-50 pips a day with 3-6 trades per day.
