# Scaling From Micros to Minis on a Funded Account
I traded micros for eight months on my funded account before I touched a single mini contract. Eight months. And I still almost blew it when I sized up.
Not because I didn’t know the math. Every trader knows 10 micros equals 1 mini. That’s not the problem. The problem is your brain treats them completely differently. One mini tick on ES moves $12.50. One micro tick moves $1.25. Same market, same direction, same setup. But watching $50 swings per point instead of $5? That rewires something in your head real fast.
When I Sized Up (Too Early)
My funded account was up about $4,200 after two months of grinding micros. Felt invincible. Switched to 2 minis on a Wednesday morning. ES was trading around the 6600 level, chopping between support and resistance like it does.
First trade worked. Made $375 in twenty minutes. Easy money, right?
Second trade.. not so much. NQ faked a breakout above 24400, I went long with 2 minis, and it reversed 30 points. Gave back the $375 plus another $400 I didn’t have budgeted for. Two trades in and I was already red on the day with size I wasn’t ready for.
Went back to micros the next morning. Ego bruised but account intact.
The 10x Multiplier Hits Different
You already know micro vs mini futures are a 10x difference in contract size. Simple multiplication. But simple math creates complicated emotions.
Trading 5 micros on ES and catching a 10-point move? That’s $62.50. Nice lunch money. Same trade with 1 mini? $125. Okay, decent. But 2 minis? $250 on a ten-point move. And a ten-point loser? Also $250. Gone.
That speed of gain and loss changes your behavior whether you want it to or not. I started cutting winners earlier because the dollar amount “felt like enough.” And I started holding losers longer because the loss “felt too big to take.” Classic symptoms of trading too much size.
What Actually Works for Scaling
Here’s what I do now, and what I tell anyone on a prop firm account who asks.
Start with micros. Build a cushion. I’m talking real cushion, not “I had two green days” cushion. Get your funded account to at least 120% of the starting balance before you even think about minis. If your account is $50K, get to $60K on micros first.
Then add ONE mini. Not two. Not “let me try a couple.” One. Trade it for two full weeks alongside your micros. See how your P&L swings feel. See if you start making dumb decisions.
If those two weeks are clean, add the second mini. Rinse and repeat.
Most prop firm accounts give you scaling plans anyway. Use them. They exist because firms watched thousands of traders blow up the exact same way. Sizing up too fast after a hot streak.
The “I Can Handle It” Trap
Every trader who blows a funded account sizing up says the same thing before it happens. “I can handle it. I’ve been profitable for weeks.”
Cool. You’ve been profitable on micros. Minis are a different game emotionally even though they’re the same market. That confidence from micro profits doesn’t automatically transfer. I’ve watched guys at Elite Trader Funding pass their eval on micros, get funded, immediately jump to minis, and fail the account in a week. Not because their strategy broke. Because their psychology did.
Size up slow. Boring slow. “Am I even making progress” slow.
Your account will thank you for it. Or don’t listen to me. I’m the guy who needed eight months to figure this out.
