Thigs you should know about all arbitrage brokers:
- Master broker should be a very low latency less than 10 ms
- Slave broker high latency over 100 ms
- you must read conditions for scalping ( sometimes broker asks to hold the positions for at least 2 minutes)
- Brokers who accept scalping doesn't mean they accept arbitrage EA.
to compare latency between broker check with your vps provider
my vps provider which are very helpful compare latency with brokers through their server in UK and USA here:
https://fxvm.net/forex-broker-latency/
Brokers server sometime they change locations, for example my broker fxpro got servers in london, amesterdam, singapore, toky, sao paolo, virginia and frankfurt and the change during the day depends on the session so latency depends on the broker's server you are connected to
I've been looking for a broker who accept arbitrage EA in REAL ACCOUNT since a while but no way, some market maker do accept but they are not regulated
Onne more thing, all arbitrage EA's show a demo account and if a real acount it runs only for 3/10 days. did you ask why????????????????????????????????
