MFF Builder Add-On FAQ
›Should I pick Default or Add-On?
Default if you've ever had a -$1k+ day. Add-On if you're confident your worst day stays under -$1k consistently. The $20 savings (Default → Add-On) buys you $500 less cushion. For most traders, paying the extra $20 for Default is correct — the math: if Add-On's tighter cushion costs you ONE additional reset over a year, you've already lost more than $20.
›Is the eval actually passable with only $1.5k MLL?
Yes — the profit target is the same ($3k) and there's no consistency rule. But the eval is structurally harder than Default's. Your minimum balance during the eval starts at $48,500 instead of $48,000.
›Funded mechanics?
Identical to Builder Default except the MLL is $1.5k throughout (eval, funded, live). Locks at +$100 above start in the same way. Same 5-payout flight path to live, same $2k cap per cycle, same 80/20 split.
