You're right, ACG also offers a free trial.
It looks like they also started allowing EAs after their approval (to avoid martingale strategies) and the main difference to FTMO seems to be that they only offer MT5 while FTMO offers additional MT4 without visible restrictions on the EA. ACG keeps the spread at 1:100 but restricts the trading volume directly while FTMO does this by reducing the spread to 1:30 on swing accounts.
I didn't read the T&C of ACG but I know that FTMOP has a diffuse clause in their T&C that they can suspend a trading account when it beleaguers the server significantly. FTMO also has a limit on the number of open positions at 200 and I don't know this from ACG (I should run a test EA on their free trial to find it out).
Yeah ACG are strict about EAs. I admit that is a significant disadvantage if they're your thing. You can use lot size calculators, trade management utilities etc. no problem, but not commercial or publically available trading robots as they break their group trading rule. But you can develop your own bot and use it if you provide them with the original mql code.
You can tick a box at purchase to enable any EA during the challenges, but they do need to be formally approved at the funding stage and as I say if they're off-the-shelf it's likely to be a No.
Yes, no martingale (adding larger size to an open position in drawdown) but that can be circumvented by stacking lots of the same size.
And average trade length must be > 2 minutes, with majority of profit from trades > 2 mins. They do this to stop HFT, all or nothing news gambling, people taking advantage of their price feed or overloading it with hundreds of trades. I suspect they have a similar clause about beleaguering (good word
) the server!
Indeed leverage is 1:100 for all products, though the indices contract size is significantly smaller than gold or forex, which can be a problem for ES/NQ traders who trade, say, 1 min with minuscule stops.
MT5 only (do people still use MT4 - it's seriously ancient now?) with CTrader soon to be integrated as a more modern alternative, with luck this month. They're also opening up their (now regulated) partnered broker to client deposits later on. Lots of progress going on there... they're a younger firm than FTMO but run by mature people with a lot of trading and financial market qualifications and experience, and it shows.
Anyway I'll stop the ACG flag-waving now but I've been with them for a good while and am very happy with almost everything about them.
