It's 10:47 a.m. in Shanghai. You're two trades into a China futures evaluation, down $95 on a $10,000 account, and rebar just printed a strong rejection candle at resistance. Every fiber of your trading brain says press. But somewhere in the back of your head there's a quieter number: $200. That's your 2% daily loss limit — and if you hit it, the evaluation day is done. Maybe the whole challenge is done.

Most traders fail futures evaluations not because their edge disappears, but because they manage the daily loss limit badly. They either ignore it until it's too late, or they fear it so much they never take a legitimate trade. Both are losing approaches. This article lays out a concrete framework for treating the 2% daily loss limit as what it really is: a structural constraint you design your entire trading system around — not an emergency brake you discover mid-catastrophe.

Why the Daily Loss Limit Is the Real Exam

Here's an uncomfortable truth about evaluations: the profit target tests your edge, but the daily loss limit tests your process under stress. Anyone can hold a winning position. The question is what you do at -$120, -$150, -$180 on a $200 limit. That's where accounts die.

The failure pattern is almost always the same. Trader takes a normal loss, say -$60. Feels behind. Sizes up on the next trade to "get it back." Takes another loss, now -$150. Now one more standard-sized loss breaches the limit, so the only mathematically available move is an oversized, revenge-style trade — usually into a market that's already moving against them. Sound familiar?

The daily loss limit doesn't create this behavior. It just exposes it faster. Which means the solution isn't "respect the limit harder." It's building a framework where you structurally cannot get into that position.

Step One: Know Your Contract Math Cold

You cannot manage a dollar-based risk limit trading contracts you haven't converted into dollars. Chinese commodity futures have specs that surprise traders used to Western products, and the tick values vary enormously. Before you place a single trade in an evaluation, you should be able to answer instantly: what does one tick of adverse movement cost me in dollars?

Here's a reference table for some of the most liquid Chinese commodity futures contracts:

Notice the spread. One lot of rebar moves in roughly $1.40 increments — you can express a precise idea with granular risk. One lot of iron ore moves in roughly $7 increments — a 20-tick move against you is already $140, most of a $200 daily budget on a $10,000 evaluation. Same account, same "one lot," wildly different risk profiles.

Convert everything to your account currency before the session starts. If your evaluation account is $10,000 with a 2% daily loss limit, your real number is $200, which is roughly 1,400+ RMB of room. Rebar gives you over a hundred ticks of breathing room. Iron ore gives you around twenty. Plan accordingly.

The 60/30/10 Framework: Budget Your Day Like a Portfolio

A daily loss limit is not a cliff you avoid falling off. It's a budget you allocate. Here's the framework we'd suggest structuring your evaluation days around:

60% — Planned Risk (Your Actual Stops)

Allocate at most 60% of the daily limit to your normal trading. On a $200 limit, that's $120. If your per-trade stop is $40, that's exactly three full-risk trades for the day. Not three-and-a-half. Not "four if the setup is really good." Three. When the budget is spent, the platform is closed — regardless of how good the next chart looks.

This is the single most important rule in the framework, because it makes the daily loss limit mathematically unreachable by normal trading. You can only breach it by breaking a different rule first.

30% — Slippage and Gap Reserve

Chinese commodity futures can move violently. Anyone who watched the 2021 thermal coal rally — where prices roughly doubled in a matter of weeks before policy intervention triggered a string of limit-down sessions — knows what policy-driven volatility looks like in this market. The 2020 oil crash, which briefly pushed certain WTI contracts into negative territory, reminded everyone that extreme moves aren't theoretical.

You will not always get filled at your stop. On fast sessions, slippage through a stop on even a mid-liquidity contract can eat several ticks. Reserve roughly 30% of your daily limit as a buffer between your worst planned day and the actual limit. If your stops execute cleanly, you never touch it. If they don't, it's the difference between a bad day and a failed evaluation.

10% — The Never-Trade Zone

The final 10% is not for trading. It's a psychological floor. When your running daily loss crosses into this zone, you stop — not because the rules force you, but because you've pre-committed to it. Traders who operate with zero buffer are forced to make their final trades at maximum emotional pressure. Traders with a floor make their last trades calmly, or better, don't need to make them at all.

Position Sizing: Work Backwards From the Limit

Most traders size positions forward: "I'll take one lot and see." Under a daily loss limit, size backward instead:

• Define your daily trade budget — 60% of the limit. On $10,000, that's $120.
• Decide your daily trade count — we'd suggest 2-4 for most evaluation styles. More than that and you're scalping noise; fewer and single-trade variance dominates.
• Divide — $120 across 3 trades = $40 of risk per trade.
• Convert to contracts — a $40 stop on iron ore (~$7/tick) means roughly a 5-6 tick stop on one lot. If your setup needs a 15-tick stop, that's a half-size position or a skipped trade.

This is also why rebar and soybean meal are such useful evaluation instruments. Their small tick values let you place tight, well-defined stops without position sizes getting awkward. Iron ore and copper demand wider stop distances per lot, which means fewer contracts and less tolerance for being early. Match the instrument to the stop, not the other way around.

Session Structure: The Chinese Trading Day Is Not One Session

A detail that catches many first-time China futures traders: the trading day is fragmented. Most Chinese commodity futures trade a day session (roughly 9:00-11:30 and 13:30-15:00 Beijing time, with a midday break) and many liquid contracts also have night sessions starting at 21:00. Some contracts have no night session at all — meaning they can gap meaningfully at the next open.

Three practical implications for daily loss limit management:

• Decide whether the night session is the same "day." Most evaluation platforms count the trading day as defined by the exchange, where the night session belongs to the following calendar day. Know exactly how your platform defines it, and when the counter resets. Ambiguity here is how traders accidentally blow through limits.
• The midday break is a natural checkpoint. If you're down meaningfully at the 11:30 break, treat the afternoon as a fresh, reduced-budget session — or don't trade it at all. Losses compound fastest in the session right after a bad morning.
• Gaps are a hidden limit risk. If you hold through a session break or into a contract without a night session, your real loss on a stop can exceed your planned loss by a wide margin. In evaluations, holding through breaks with an open position is rarely worth the risk.

Rules for the Bad Day (Write These Down Before You Need Them)

The framework above handles normal variance. These rules handle the abnormal day — and they only work if they're decided in advance:

• Two consecutive stop-outs = done for the day. Not three. Two losses in a row means either the market isn't reading your setup or you aren't reading the market. Either way, the next trade has negative expectancy.
• No size increases on a losing day, ever. The "double to recover" instinct is the single largest destroyer of evaluation accounts. Recovery trades are allowed at normal size or smaller — never larger.
• Define a daily profit stop too. If you're up 1.5%+ on the day, consider protecting it. Giving back a strong day chasing more is a slower version of the same discipline failure.
• Journal the limit, not just the trades. Each evaluation day, log your max intraday drawdown against your 60% budget. If you're consistently using 90% of your planned risk, your stops are too wide or your count is too high — fix the system, not the willpower.

The goal of a daily loss limit framework isn't to never have a bad day. It's to make sure a bad day costs exactly what it was designed to cost — and nothing more.

Putting It Together: Your Pre-Session Checklist

Before every evaluation session, run this in under two minutes:

• Daily limit in dollars: known. 60% budget: calculated. Trade count: fixed.
• Contracts on watchlist: tick values converted to account currency.
• Stop distance per setup: defined, converted to contracts, verified against budget.
• Night session plan: trading or flat — decided before the day session opens.
• Hard stop rules (two losses, no size-ups, buffer floor): written where you can see them.

None of this is glamorous. That's the point. Passing a futures evaluation is rarely about finding a better setup — it's about making your worst day survivable so your best days get to count. The 2% daily loss limit, treated as a design constraint rather than a threat, becomes the very thing that forces the discipline that profitable trading requires anyway.

If you want to pressure-test this framework against real market conditions, you can run it through a China futures evaluation on real historical data at XS Select, with challenges starting from $29. The market data is real, the loss limits are real, and the discipline you build is the kind that carries over. Trade the framework, not the feelings.
