Even though my time is limited when it comes to scalping ( I like to do it when London's session opens, around 3am here where I live) so far this is the best scalping technique I've come across but it also depends on the person, if you can eliminate the choppy charts and crazy spikes (like around news releases) then you should be able to be profitable. I do have a job with a crazy schedule but I might be able to scalp for a couple of days next week we will see how it goes, I will post my results if I do trade. One thing I'm going to do different is I'm going to enter 2 orders with the same s/l of 10 to 12 pips depending on the pair that I'm trading, with a t/p twice of that with one order and leave the other opened and move the s/l 10 pips above or under the entry price when the first order gets hit. I don't trade more than 2 pairs at the same time but I use it in every pair as long as they have a spread of no more than 3 pips. You should test it yourself and see how it could work for you. You can also paper trade it with trade interceptor (paper trading is different from demo trading, TRADE INTERCEPTOR | FOREX VIDEOS) you can paper trade on the weekends if you want, when using trade interceptor. Because it goes by candle and not by tick to tick, just make sure when you see a candle with the bottom or top almost touching the 7 ema ( this where you would enter) take notice of the low of that candle and go back one candle and put an entry order so you can be more exact on your entry, if you don't then when you enter it will enter at the price the candle closed at, this is better then using mt4 by going back and look at possible entries because you don't see the next candle and you get to see how your trade develops as if it was real, trade interceptor uses historical data it's not simulated data, you get to choose the day in the past that you want to trade. It's a good way to practice in the weekends anyway.
By the way paper trading with trade interceptor pauses automatically every time you enter a trade or hits the s/l or t/p you have click play again after it does any of these.
