Friday was the best day of this challenge. Six trades, six winners, +$336.49, a 6/6 discipline sheet. I wrote a whole post about finally running the program as written.
Monday I took three trades and gave all of it back, plus interest. Net -$379.66. And here’s the part that stings: I didn’t revenge trade, I didn’t chase, I didn’t overtrade. My emotional state was logged green on all three. The setups were the same zone-expansion trigger I’ve been using for two weeks.
I just traded the wrong instrument in a size it was never possible to trade correctly.
Account snapshot — Day 16
- Balance: $48,763.74 → $48,384.08
- Day P/L: -$379.66 across 3 trades (1 winner, 2 losers)
- Maximum Loss Limit: $48,000.00 — drawdown cushion $384.08, the tightest of the entire challenge
- Risk per trade: $50 (1R). Daily cap: $250 (5R)
- Today’s loss in R: -7.6R — 152% of the daily cap
- Discipline score: 4/6, Warning band
- Cumulative payouts: $0 / $100,000
That cushion number is the one that matters. $384.08 is less than what a single one of today’s two Canadian dollar trades cost me. I am one trade away from failing this account, and I got there on a day I was calm.
The three trades
All three were Globex-session shorts entered Sunday evening into Monday’s overnight, and all three were closed Monday afternoon.
Trade 1 — 6C short, 1 contract, -$259.22 (-5.18R)
Entered 0.71950 Sunday at 4:18 PM. Exited 0.72205 Monday at 2:11 PM. That’s a 0.00255 adverse move, held for nearly 22 hours.
Trade 2 — 6C short, 1 contract, -$219.22 (-4.38R)
Same instrument, same idea, entered 0.71990 at 6:55 PM. Exited at the same 0.72205 at the same 2:11 PM. A second entry into a position that was already going against me.
Trade 3 — MYM short, 1 contract, +$98.78 (+1.98R)
Entered 53,468 at 11:05 PM, exited 53,268 at 2:12 PM. A 200-point move on the micro Dow, exactly the setup working exactly the way it should. This is what the strategy looks like when the instrument fits the plan.
One good trade. Two bad ones. And the two bad ones combined to -9.56R on a plan where the entire day is supposed to stop at -5R.
The actual problem: 6C was never tradeable at my risk level
This is not a “I got the direction wrong” story. This is arithmetic I should have run before I ever clicked the button.
The CME Canadian dollar future (6C) is a 100,000 CAD contract with a minimum tick of 0.00005, worth $5.00 per tick (Canadian Dollar futures specs, CME Group).
My 1R is $50. Divide $50 by $5 per tick and you get 10 ticks of stop room. Ten. That’s my entire risk budget on one 6C contract.
Trade 1 moved 51 ticks against me. Trade 2 moved 43 ticks. So the stops I actually used were four to five times wider than 1R allows on that instrument — and there is no micro Canadian dollar contract to scale down into. There is no correct size for 6C in a $50-risk account. One contract is already too big.
Which means the honest version of today’s decision isn’t “I sized too large.” It’s “I traded an instrument that doesn’t exist inside my risk plan.” That’s the same conclusion I reached about gold on Day 9, when one MGC contract cost $152 at the day’s ATR and I traded it three times anyway. I put gold on the off-menu list and then never audited the rest of my watchlist for the same problem.
The counterfactual
Two ways to run today over again:
- Sized to 1R (both 6C stops capped at $50): -$50 -$50 +$98.78 = -$1.22. Essentially flat.
- 6C off the menu entirely, since no size fits: just the MYM trade = +$98.78. A green day.
Same reads. Same setups. Same conviction. Same session. The only variable I changed was position sizing, and the day swings from -$379.66 to somewhere between breakeven and green. That’s a $478 swing produced by nothing but arithmetic.
Process check — 4/6, Warning
Here’s the uncomfortable scorecard. Rules followed: yes. Emotional control: yes. Journal complete: yes. Reset used: yes. Risk followed: no. Max loss respected: no.
Four of six boxes green, and the two red ones cost more than a full week of good process. This is the mirror image of Day 8, where I had perfect discipline and a small loss. Today I had good behavior and a bad number, because behavior and sizing are two separate systems and only one of them was working.
New rule-break row going into the log: cost -$478.44, trigger “traded an instrument that doesn’t fit 1R,” rule broken “position sizing,” prevention rule “convert the ATR stop to dollars before entry — if one contract’s stop exceeds $50, the instrument is off the menu.” The reset rule did fire, which is why I stopped at three trades instead of trying to win it back the way I did on Day 13.
August in review: the month the outliers ate
August is done, and it was a losing month: -$1,615.92 over 16 trading days.
The weekly breakdown: Week 3 -$766.68 on 59 trades, Week 4 +$84.06 on 72 trades, Week 5 -$553.64 on 37 trades, and today’s -$379.66 on 3. Sixteen days, 129 journaled trades, 171 broker fills.
The aggregate stats:
- Win rate: 38.0%
- Profit factor: 0.68
- Avg win $53.69 vs avg loss $48.17 — a 1.11 ratio
- Avg R per trade: -0.25
- Avg discipline: 4.75/6 — 10 Process days, 2 Stand-down days
- Rule breaks: 6 logged (0.38/day)
- Journal completion: 100%
- Best day: +$336.49 (Day 15). Worst day: -$719.27 (Day 13)
Now here’s the number that reframes the whole month for me. Average loss is $48.17. My 1R is $50. On average, my losses are sized correctly. Average win is $53.69, about 1.07R. So the typical trade in this account is behaving roughly the way the plan says it should.
So where did $1,600 go? Three incidents:
- Day 13’s revenge-trading cluster: -$719.27
- Day 14’s oversized 3-contract MES short: -$191.16
- Today’s two 6C shorts: -$478.44
That’s -$1,388.87 — about 86% of the entire month’s loss in three sizing and impulse failures. Strip them out and the other 126 trades across 16 days netted roughly -$225. Not profitable, but survivable. Nowhere near account-threatening.
I spent most of August thinking I had a strategy problem. The data says I have a tail-risk problem. The edge isn’t great yet, but it isn’t what’s killing the account. Three days out of sixteen are.
Lesson of the day
Think about walking into the grocery store with $50 and a list.
You follow the list perfectly. Nothing impulsive, nothing off-plan, no candy bar at the register. Every single item in the cart is something you wrote down before you walked in. Then you get to the checkout and the total is $250, because you grabbed the family-size of everything instead of the single-serve.
You didn’t have a discipline problem. You had a portion problem. And the receipt doesn’t care about the difference.
That was today. My list was right. My selection was right. My emotional state was right. I bought the family-size of an instrument that only comes in family-size, and the receipt was 152% of my daily budget.
Most trading-discipline content is about resisting the impulse — don’t chase, don’t revenge trade, don’t force it. That’s the loud failure mode and I’ve written about it plenty in The Mistakes Files. But there’s a quiet failure mode that never feels like a mistake while it’s happening: doing everything right at a size that makes being right irrelevant.
The fix isn’t willpower. It’s a calculation you run before the trade exists. Stop distance in ticks, times dollars per tick, times contracts. If that number is bigger than 1R, you don’t have a trade — no matter how good the chart looks.
September plan
New month, $384.08 of cushion above the Maximum Loss Limit. September’s job is not to make money. It’s to not fail.
- Audit the entire watchlist for 1R fit, tonight. Every instrument gets the same math 6C just failed: ATR-based stop in ticks × dollars per tick. Anything where one contract can’t fit inside $50 goes on the off-menu list next to gold and 6C. I should have done this on Day 9.
- Dollar risk gets stated out loud before entry, not contract count. “One contract” told me nothing today. “$255 of risk” would have stopped me.
- Overnight carries get the same sizing math as intraday. All three of today’s trades were held 15–22 hours. Holding a position through a session I’m not watching doesn’t loosen the risk rule — it tightens it.
- One entry per instrument per idea while the cushion is under $500. The second 6C short was an add into a losing position dressed up as a second setup.
- Log the break the day it happens. The rule-break log still ended August 27 when I sat down to write this. Same gap as Day 9.
Takeaway
A clean day and a correct size are two different achievements. You can earn one and still lose the month on the other.
Before your next trade, do this: take the stop distance, multiply it by the dollars per tick, multiply by contracts, and say the number out loud. If it’s bigger than one unit of your risk, the trade doesn’t exist. Not smaller — nonexistent. Some instruments simply aren’t available to your account size yet, and pretending otherwise is how three good days get erased by one calm one.
Then go pull your own month and check what percentage of your loss came from three trades. If it’s most of it, you don’t need a new strategy. You need a size rule you actually run the math on.
