Timba, a scalp is more experience and psychology than anything else. It works on currencies if you're quick enough, but it can also scalp you. What you look for is market moving events like economic data releases, you look at your primary trend and most often your scalp will be in the opposite direction because of a pop 'n drop or other way round, then you lok if you're at a psuchologically significant level ie 1.4300 for EURUSD or USD1250 for Platinum etc. Now if the level breaks then the market usually rushes through it to at least the first fibo extension, pauses and swings right back, often to the first fibo beyond the mark before it continues the primary trend. The aim is to ride the whipsaw, but it hellova risky and I've lost as often as I've won. It takes a lot of experience to get this right and I'm nowhere near it
