# 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](https://propwhisperer.com/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](https://propwhisperer.com/position-sizing-futures-one-more-contract/).
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](https://propwhisperer.com/trading-micros-on-a-prop-firm-account/) 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](https://elitetraderfunding.com) 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.
