i think the best platform for scalping which always ensure most lowest trading spreads , only lowest trading spread's can bring profit by scalping.
A low trading spread is more preferable for scalping trading because it's only needed the smallest tick movement in the instrument trading pair, usually, I like scalping in EURUSD this is included in USD pairs that most have the lowest spread.
In my view, the best trading platform for scalping is the FP Markets MT4 account because the broker has one of the tightest spreads, and the MT4 platform is best suitable for scalping.
MT4 is the most popular trading platform as many brokers offer the platform, but not all broker allow scalping, and different broker maybe has different connection speed to instant market order, broker market maker usually will face requote problem although use MT4 trading platform, FXOpen included broker obtained certificate quality execution from Financial Commission.
For better scalping, best to look for brokers that offer tight spreads, you can check out myfxbook for spreads comparison. Check out the spreads of fxview, icm and xm on that.
you can compare different broker on live time and check the best one IC markets do offer tight spreads and low brokerage
The one that's worth to try in my view is Hotforex since it offers wide range of instruments and very low spreads on major pairs which is ideal for scalping and news trading.
I'm a scalper trading with FP Markets after doing several research. It is a suitable broker for scalping because the spreads average at 0.0pips for most parts of the day. Commission costs and slippages are lower compared to other similar ecn brokers, which is an advantage for many scalpers.
Scalping needs instant market execution, especially manual scalper choose broker low spread is a good way to trying catch profit at a short time, not broker allow scalping, so as a trader needs to make sure if they allow scalping trade, an expert scalping, they can win on the contest.
