Since I'm a scalper, the MT4 platform is much suitable because of its simple trading software and tools.
I trade with FP Markets MT4 platform mainly for their low spreads, and the MT4's combination makes it easier to predict trades with the MT4's built-in technical indicators, with nine timeframes to choose from when placing orders.

Acttrader - Have seen this with fxview too but never tried it, I am a mt4 guy as my system is 32-bit but thinking of upgrading it. Though the mt4 thing is working fine for me till now but soon try mt5 for more timeframes and mql5 support.
