It's 10:47 on a Tuesday morning. You're two trades into your evaluation, down 1.4% on the day, and you've just watched iron ore reject off a level you were certain would break. The itch to "get it back" before lunch is physical. One more entry, slightly wider stop, double the size — and suddenly you're staring at a breached daily loss cap, a failed evaluation, and the same sentence every blown trader has ever typed into a journal: "I knew I shouldn't have taken that trade."

The 2% daily loss cap is the single most common reason otherwise competent traders fail futures evaluations. Not because the cap is unfair, but because almost nobody builds their trading around it. They build their strategy first and treat the cap as an afterthought. Let's flip that order.

What a 2% Daily Cap Actually Tells You About Your Trading

Before we talk tactics, understand what the rule is really measuring. A daily loss cap isn't a punishment — it's a proxy for whether you can survive a bad day without catastrophic behavior. On most China futures evaluations, hitting the cap ends your day or your challenge outright. That means your real constraint isn't your win rate or your edge. It's this: your worst normal day must fit comfortably inside 2%.

Work backwards from that. If your typical stop is worth 0.8% of your account per trade, then two losses and a slippage event put you at the edge of the cliff. If your typical stop is worth 0.3%, you can absorb four full losers, one partial, and still have room to trade your plan the next morning. Same strategy, same edge — completely different survival profile.

This is why the cap changes everything about how you should approach Chinese commodity futures. The instruments themselves are volatile enough that a casual approach to position sizing gets punished fast.

Know Your Instruments: The Contract Math That Decides Everything

You cannot size positions around a 2% cap without knowing exactly what one tick costs you. Here are the specs for the most-traded Chinese commodity futures contracts, straight from the exchanges:

Now run the numbers. Say your evaluation account is ¥200,000 and your cap is 2% — that's ¥4,000 of daily risk budget. One lot of iron ore with a 20-tick stop risks ¥1,000. Three losing iron ore trades at that stop size and your day is over at 75% of the cap. One lot of rebar with a 15-tick stop risks ¥150 — you could take that same setup ten times and stay inside the cap.

Notice what this means: the same 2% rule produces completely different trade frequency limits depending on which contract you trade and where you place your stop. Iron ore is a precision instrument. Rebar is a volume instrument. Treating them identically is how accounts die.

Trade Frequency: The Three-Tier Risk Budget

Here's the framework I'd suggest for anyone trading a futures evaluation with a hard daily cap. Divide your daily risk budget into three tiers:

• Tier 1 — Core risk (60% of the cap). This is your budget for your A+ setups, the ones you'd take with full conviction. On a ¥4,000 budget, that's roughly ¥2,400 — enough for two or three properly sized core trades.
• Tier 2 — Opportunity risk (25% of the cap). B-grade setups, or adding to a winner that's working. If Tier 1 is spent, these get smaller size or get skipped.
• Tier 3 — Survival buffer (15% of the cap). This money is not for trading. It exists to absorb slippage, gap-throughs on stops, and the fee drag of a busy session. If you're dipping into Tier 3, you're done for the day.

The tier system does two things. First, it front-loads your best ideas — you're always taking your highest-conviction trades while your risk budget is intact, not after you've bled half of it chasing B-setups. Second, it converts the cap from a wall you crash into into a budget you spend deliberately.

On frequency specifically: for most traders I'd cap it at three to five trades per day during an evaluation, full stop. Chinese commodity futures sessions have distinct rhythm — the night session, the morning session with its midday break, the afternoon session — and it's tempting to treat each as a fresh opportunity. Don't. The cap doesn't reset at the midday break.

The Two-Loss Rule

Add one hard override: two consecutive full-stop losses ends your trading day, regardless of how much budget remains. Two straight losers means either the market isn't matching your read today, or you're not matching the market. Either way, the third trade is statistically your worst. Every experienced trader knows the feeling of the "revenge third trade." Make the decision at zero emotional cost — in your written rules, before the session opens — instead of in the moment at maximum emotional cost.

Stop Placement: Why Your Stop Must Serve the Cap, Not Just the Chart

Standard stop-placement advice says: put your stop where the trade idea is invalidated. That advice is correct and incomplete. During an evaluation, your stop has two jobs: invalidation and budget compatibility. If the technically correct stop is so wide that one loss consumes half your daily budget, you don't get to take that trade at full size. You have three honest options:

• Skip it. The most underrated skill in evaluation trading. A trade that risks 1.2% of your account on a 2% cap day is a coin flip with your challenge attached to it.
• Shrink the size until the risk fits. If the setup needs a 30-tick stop on iron ore (¥1,500 per lot) and your per-trade budget is ¥750, trade half lots or pass. Same trade, half the damage if wrong.
• Find a tighter structural level. Sometimes a pullback entry closer to your invalidation point lets you use the same stop distance in price terms but a much smaller risk in money terms. This is the legitimate version of "getting a better price" — you're not predicting, you're repositioning.

What you should never do is tighten the stop below your structural invalidation just to fit more trades into the budget. That's the worst of both worlds: you take the trade AND you get stopped out on noise before the idea can work. A too-tight stop converts a good setup into a guaranteed loser through churn — three 10-tick stops on rebar cost you the same as one 30-tick stop, except now you've paid fees three times and lost your read on the market.

Respect the Volatility Regime

Stop placement in Chinese commodity futures has to account for regime shifts, because this market produces them. The 2020 oil crash showed the world what a genuine liquidity vacuum does to stops — and while crude isn't a Chinese exchange product, the same dynamic played out domestically in the 2021 thermal coal rally, when policy intervention and supply dynamics produced moves so violent that exchanges repeatedly raised margin requirements and adjusted trading limits mid-trend. Traders with stops calibrated to "normal" volatility got filled far beyond their intended risk.

The lesson for your evaluation: when a product is making historically unusual moves — daily ranges several times their recent average, or the exchange is adjusting margins — your normal stop distances are obsolete. Either widen your risk accounting accordingly (which usually means trading smaller or not at all) or sit out. The cap doesn't care that "the market was crazy." It only cares about the number.

A Practical Daily Routine Built Around the Cap

Pull this together into something you can actually run tomorrow:

• Pre-session: Write down your daily risk budget (2% minus expected fees and slippage — call it 1.8% of usable risk). Assign your Tier 1/2/3 amounts. Identify the one or two contracts you'll trade and note their tick values.
• Pre-trade, every single time: Calculate risk = stop distance in ticks × tick value × lots. If it exceeds your current tier budget, resize or pass. No mental math shortcuts, no "it'll probably be fine."
• After any loss: Recalculate remaining budget out loud or on paper. This 10-second habit is what stops the spiral.
• After two consecutive full losses: Platform closed. Journal notes. Done for the day.
• End of session: Log every trade with its risk in percentage terms. Over a week, you'll see your true frequency and your true average risk per trade — and whether your strategy actually fits inside the cap or whether you've been surviving on luck.

One more frequency note: passing an evaluation is a marathon at a sprinter's discipline. You do not need to trade every day. Chinese commodity futures will offer clean setups on rebar or soybean meal next week just like they did this week. The traders who pass evaluations are not the ones with the most trades — they're the ones whose worst day would look boring on a statement.

The Mindset Shift That Makes the Cap Work for You

Here's the reframe that changes everything: the 2% cap is not a limit on your losses. It's a specification for your strategy. A strategy that routinely risks 1% per trade with five-trade days doesn't "struggle with" the cap — it's simply incompatible with it, the way a V8 engine is incompatible with a fuel-efficient sedan. The fix isn't willpower. It's redesign: smaller per-trade risk, fewer and better trades, stops placed at structural levels with size adjusted to fit the budget.

Traders who internalize this stop viewing the cap as an enemy and start using it as a filter. It filters out the revenge trades, the oversized positions, the "just this once" wider stops. Every rule that protects the cap protects your long-term trading career too — because the habits that pass an evaluation are the same habits that keep you in the market for years.

And one honest caveat: no framework survives contact with live markets unchanged. Your stop distances, your tier percentages, your two-loss rule — all of it needs testing against real price action, not just theory. If you want to pressure-test your system on Chinese commodity futures — to trade rebar, iron ore, and the rest of the board under a real daily loss cap with real market data — that's exactly what we built the evaluation at XS Select for. You can run your rules through a China futures evaluation starting from $29 and find out whether your strategy and the cap are actually compatible, before any real capital is on the line.

Trade the budget, not the itch. See you in the evaluation.
