Forex scalping is a short-term trading strategy that attempts to make a profit out of small price movements within the forex market. Scalpers will buy and sell a foreign currency pair, only holding the position for a period of a few seconds or minutes.
Before selecting a broker, rectify your trading strategies. Personally, I prefer scalping the most and the broker ensures all scalping-genial trading facilities.
I would recommend ICT or Smart Money Concepts. Look him up on youtube, The strategy is fairly simple but requires a lot of self control and discipline .
