Scalping can be done and can be profitable, I scalp and have done for many years, for me I like to be flat at the open and close of play. It took me a long time to define my scalping system, the system is rigid for entry, exit and stops.
I trade the AUD/USD & EUR/USD on a higher Tick count for a +10 Profit /- 7 Stop.
AUD/USD has set up 7 times today, winning 6 and losing 1, (Nett 63 pips)
EUR/USD has set up 13 times today winning 7 and losing 6 , (Nett 28 pips)
Its is tiring and you are glued to your screen, and I accept thats not for everyone, just suits my style of trading.
I also use the same tick count system on the DAX, on a +15 profit / -7 stop, 2 Trade set ups today for + 30 pips.
If you want to scalp, keep at it, drop me a pm and l'll pass across the tick setting l use for you to play around with.
Good luck
