We’ve all been there. You are three days into a futures evaluation, up 4%, and feeling like you have finally cracked the code. Then, a sudden headline hits the tape, the market gaps, you freeze, and by the time you look at your P&L, you’ve blown the daily loss limit. Game over. You didn’t just lose money; you lost your chance at funding.

When you transition from casual retail trading to a funded evaluation, the rules change. The most critical rule is usually the daily loss limit—often set at 2% of your initial account balance. It sounds generous until you realize how fast a high-leverage market can chew through it. If you are looking to trade China futures, where volatility and contract multipliers can be unforgiving, understanding how to mathematically and psychologically respect that 2% limit is the difference between passing and failing.

The Anatomy of a 2% Daily Loss Limit

The 2% daily loss limit is not a suggestion; it is a hard circuit breaker. Prop firms use it to protect their capital from rogue algorithms, black swan events, and—most commonly—traders going on tilt. If your evaluation account is $10,000, your daily limit is $200. In the world of Chinese commodity futures, where margin requirements can be leveraged 10-to-1 or higher, $200 can vanish in a matter of minutes if you are over-leveraged.

It is vital to distinguish between the daily loss limit and the maximum drawdown limit. The max drawdown is your overall runway (often 4% to 10% depending on the platform). The daily limit is your daily leash. You can be a fantastic market analyst, but if you lack the tactical discipline to cut a losing day short, you will never survive long enough to let your winners run. You must treat the 2% limit as an absolute maximum, not a target. Your personal daily stop should realistically be around 1% to 1.5%, giving you a buffer against slippage and exchange fees.

Sizing Your Bets for Chinese Commodity Futures

Substance over theory: you cannot manage a 2% limit without knowing your contract specs. Let’s break down a few heavily traded markets so you can see exactly how position sizing works in practice.

Rebar (SHFE)

Rebar is one of the most liquid construction contracts in the world. Traded on the Shanghai Futures Exchange (SHFE), the standard contract size is 10 tons per lot. The minimum tick size is 1 RMB per ton. Therefore, every single tick movement equals 10 RMB. If the exchange rate is roughly 7.0 RMB to 1 USD, one tick is about $1.42. If your daily max loss is $200, you can only afford to lose about 140 ticks in a day. If your stop loss on a rebar trade is 20 points (20 ticks), you can only risk a maximum of 7 lots on that single trade.

Iron Ore (DCE)

Traded on the Dalian Commodity Exchange (DCE), iron ore is a beast. The contract multiplier is 100 tons per lot, and the minimum tick size is 0.5 RMB per ton. This means every 0.5 point move equals 50 RMB (around $7.14). Iron ore is notoriously volatile. A standard intraday range can easily be 20 to 40 points. If you are caught on the wrong side of an iron ore move, a 10-point adverse excursion on just 3 lots will cost you 3,000 RMB (around $428). On a $10,000 account, that single trade just blew your 2% daily limit. When you trade rebar/iron ore, you must calculate your lot size based on your stop-loss distance, not your account margin.

Crude Oil (INE)

The Shanghai International Energy Exchange (INE) crude oil contract has a multiplier of 1,000 barrels per lot and a tick size of 0.1 RMB. Each tick is 100 RMB (around $14.28). If you want to trade crude oil, you must realize that two or three bad entries can end your evaluation day instantly.

Rule of thumb: Calculate your maximum allowable lots per trade using this formula: (Daily Loss Limit in RMB) / (Stop Loss in Ticks * Tick Value in RMB). Never exceed this lot size.

The Danger of Overnight Gaps and Limit Moves

One of the most unique risks when trading Chinese commodity futures is the daily price limit system (涨跌停板). Exchanges set maximum allowable price moves per day to curb excessive speculation. While this sounds like a safety net, it can be a trap for traders holding overnight positions.

If you are holding a long position and the market hits limit-down the next morning, there are no buyers. Your stop-loss order will not fill because the price is locked. You are trapped, forced to watch the market close against you, and you will open the next day with a massive gap—almost certainly violating your daily loss limit on day two.

Consider historical precedents. During the massive 2021 thermal coal rally on the Zhengzhou Commodity Exchange (CZCE), the market experienced consecutive limit-up days. Short sellers who were caught leaning against the trend had no way to exit. Their losses compounded daily. Similarly, during the 2020 global oil crash, INE crude oil futures experienced unprecedented volatility, proving that wide stops can easily exceed your daily 2% threshold in a single session.

The lesson? If you are in an evaluation, avoid holding massive overnight positions in highly volatile contracts unless your position size is so small that a limit-down move still leaves you well under your 2% daily threshold.

Tactical Execution: Cutting Losses Before They Cut You

Math is only half the battle. The other half is psychology. How do you practically ensure you don't hit that 2% wall?

• Hard Daily Stops: Do not rely on your willpower to stop trading. Set an alarm or a hard rule: if your closed P&L plus open risk reaches 1.5% of the account, you shut down the trading platform for the day. Walk away. The market will be there tomorrow.
• Avoid Averaging Down: The fastest way to blow a daily loss limit is to add to a losing position hoping for a bounce. In leveraged futures, averaging down turns a small surgical loss into a catastrophic amputation. If your thesis is invalidated, exit.
• Time-Based Stops: If you enter a trade and the market immediately goes dead sideways, your thesis isn't playing out. Consider exiting before the market decides to break out violently against you. Dead money ties up your mental bandwidth for the rest of the day.
• Scale Out of Winners: While this doesn't directly prevent losses, scaling out secures profits early in the day. Once you have booked a green day, you can lower your risk tolerance for subsequent trades, ensuring you don't give back gains and accidentally flirt with the loss limit.

Practical Application: Building Your Daily Risk Framework

Let’s put this into a practical framework you can use before you place your next trade in a futures evaluation.

If you follow this framework, hitting the 2% daily loss limit becomes mathematically improbable unless you suffer catastrophic slippage on a limit move—which you mitigate by not holding oversized overnight positions.

Closing Thoughts

Passing a trading evaluation isn't about hitting home runs; it's about hitting singles and doubles while avoiding strike-outs. The 2% daily loss limit is the ultimate test of your discipline. It forces you to trade like a risk manager first and a trader second. By understanding the exact contract specs of the Chinese commodity futures you are trading, respecting the danger of limit moves, and implementing a rigid daily risk framework, you tilt the odds in your favor.
