It is a lot of traders use arbitrage strategies, because arbitrage strategies continue to lead in profitability at low risk.  And the most important problem with this kind of trading is the broker. Major forex brokers prefer traders who lose money and for this reason they are in every possible way try to prevent successful trading.

Arbitrage trader should understand several very important sings:

1. Arbitrage is absolutely legal trading stile and it will be better to use regulated brokers and in this case your money will be safe;
2. You have good chance to make money for long time, if you use locking arbitrage strategy or hedge arbitrage strategy instead of latency arbitrage.

An illustration to the second point can serve as a screenshot from myfxbook

Duration of major trades higher the 1 hour. If you use standard Latency arbitrage strategy your trades duration will be <1s

and  profit  up to 125 pips (Data includes last 200 transactions based on the analysed history.)  If you use standard Latency arbitrage strategy your trades duration will be <2 pips

This style of trading can not be attributed to arbitrage and even scalping and is most like a grid trade.
