I don’t use any indicator or EA to scalp. I would rather stick to my Price Action trading as I don’t know what algorithm they used, how good they were and lot more. I think scalper should more focused on their Broker. Low spread, lower the slippage is much better during news. You really should find if your broker allows scalping before creating account. My broker (Hanseatic Broker) has no problem with scalping.
If you want to make money scalping the markets with HFT (high frequency trading), then you most certainly are going to want a fully automated system. My suggestion is to build a custom solution tailored to your own specific needs. There is no single indicator alone which will work for you, it also requires a good deal of experience, and a solid trading strategy.
If it looks too good to be true, it's probably a scam! Let the buyer beware.
Some of the most commonly used forex indicators for scalping are the simple moving average (SMA) and the exponential moving average (EMA). These can be used to represent short-term variance in price trends of a currency.
