I use FXOpen broker for scalping robot, the company regulated on ASIC< FCA and Cysec, offer low spread mainly on the USD pairs instant execution very fast no delay, good for scalping in my experience use robot scalping.
Another topic related to scalping... You need to look not only for spreads, but also for execution speed. I don't think you can find the best result for you on the forums. Create a list of the most reliable brokers for you, preferably with a long history, and test each one until you find an option that suits you. The time spent will pay off when your trading is profitable.
Security is a major issue when it is time to choose a right broker, basically we think only regulated trading broker guarantee their clients funds. But practically regulation is not a big deal; the main issue is a credibility. Actually the credible trading broker always makes sure security of funds at any kinds of investments with a wide range of trading technologies.
