Just here to say Good luck, ive just started the FTMO challenge myself and opted in to trade my manual algorithm instead to minimize any risk of going over the daily limit.
My intention is to use FTMO to help supplement my algo accounts rather than run EA's on the actual FTMO account.
Even if you do decide to run EA's on on FTMO challenge, make sure you're keeping an eye on it as if you're used to raw spreads, then youll get a shock when you try to trade on the FTMO accounts whether its the challenge or the real account.
Either way, good luck! I hope you smash it!
