You are three hours into the session. The Shanghai Futures Exchange (SHFE) open has been volatile, and you caught a beautiful trend on Rebar (RB). But then, a sudden reversal hits. You hold through what you thought was noise, only to watch your P&L slide from +150 CNY to -800 CNY in minutes. Then, the screen flashes red. You are out. Not because your strategy failed long-term, but because you violated the 2% daily loss cap.

This is the most common reason traders fail China futures evaluations. It is not a lack of edge; it is a lack of structural discipline. In the world of prop trading, specifically for Chinese commodity futures, the daily loss limit (DLL) is not just a guideline—it is a hard boundary that separates funded traders from those who remain in the evaluation phase. The 2% cap is tight, especially given the leverage inherent in futures. But it is manageable if you treat risk management as a mechanical process rather than an emotional decision.

Here is how to survive the 2% daily loss cap while trading high-liquidity instruments like Rebar, Iron Ore, and Crude Oil.

Understanding the Math: What Does 2% Actually Mean?

Before you place a single order, you must translate the percentage into contract quantities. Many traders fail because they think in terms of "points" or "ticks" without converting them back to their account equity. Let’s break down the math using a standard evaluation account size.

Assume you are trading a $10,000 evaluation account. A 2% daily loss cap means you cannot lose more than $200 (or the equivalent in CNY, depending on the platform’s base currency) in a single trading day. If you hit that number, your account is terminated. This is non-negotiable.

To survive, you need to know exactly how much one contract is worth and how many ticks it takes to hit your stop loss. Let’s look at two of the most popular contracts for global traders accessing Chinese commodity futures:

Case Study 1: Rebar (RB) on the SHFE

Rebar is the backbone of the Chinese construction sector and highly liquid.

• Contract Size: 10 tons per lot.
• Tick Size: 1 CNY per ton.
• Tick Value: 10 CNY per tick (10 tons x 1 CNY).

If your stop loss is 10 ticks away from your entry, your risk per contract is 100 CNY. If your evaluation account is denominated in CNY and you have a 20,000 CNY account (approx $2,800 USD), your 2% daily loss limit is 400 CNY. This means you can only afford four losing trades of 10 ticks each, or one losing trade of 40 ticks, before you are out for the day. There is no room for "averaging down" or widening stops.

Case Study 2: Iron Ore (I) on the DCE

Iron Ore is volatile and often moves in larger ranges than Rebar.

• Contract Size: 100 tons per lot.
• Tick Size: 0.5 CNY per ton.
• Tick Value: 50 CNY per tick (100 tons x 0.5 CNY).

This is where many traders blow up. A standard 20-tick stop loss on Iron Ore costs 1,000 CNY per contract. On a small evaluation account, one bad trade on Iron Ore can instantly breach the 2% cap. If you are trading Iron Ore in a small account, your stop loss must be extremely tight, or your position size must be fractional. If the platform does not allow fractional contracts, you may need to avoid Iron Ore entirely until your account size is larger.

The One-Trade Rule: Pre-Calculate Your Maximum Position Size

The biggest mistake evaluation traders make is sizing positions based on "feeling." They look at the chart, see a setup, and think, "I'll take two contracts." This is dangerous. You must reverse-engineer your position size from your risk limit.

Adopt the Fixed Dollar Risk Model. Before you enter any trade, ask yourself: "What is my maximum dollar risk for this specific trade?"

If your daily loss limit is $200, you should never risk more than 25-50% of that limit on a single trade. This ensures that even if you lose two or three trades in a row, you still have capital left to trade the next day. For our $10,000 account example:

• Daily Loss Limit: $200.
• Max Risk Per Trade: $50 (25% of the daily limit).
• Calculation: If you are trading Rebar (10 CNY/tick), and your stop loss is 5 ticks, your risk is 50 CNY. You can trade 1 lot. If your stop loss is 10 ticks, your risk is 100 CNY. You cannot trade this setup unless you reduce your lot size (if permitted) or widen your account.

By capping the risk per trade at 25% of your daily loss limit, you give yourself four consecutive losing trades before you hit the wall. This creates psychological breathing room. You are no longer afraid of one loss, because you have planned for it.

Volatility Matters: Adjusting Stops to Market Conditions

Chinese futures markets are not static. The volatility of Rebar in January is not the same as in July. Iron Ore reacts violently to news from Australia and Brazil. If you use a fixed stop loss (e.g., "always 10 ticks"), you will be stopped out by market noise in high-volatility periods and exposed to large losses in low-volatility periods.

Instead, use ATR (Average True Range) to define your stop loss. The ATR indicator tells you the average movement of the asset over a specific period. A common rule is to set your stop loss at 1.5x or 2x the ATR.

However, this must be filtered through your position sizing rule. If the ATR is high, your stop loss will be wider. To keep your dollar risk constant, you must reduce your position size. Conversely, if the market is quiet and the ATR is low, you can increase your position size while keeping the dollar risk the same.

"High volatility does not mean you should take bigger losses. It means you should take smaller positions."

For example, if the ATR for Iron Ore spikes due to a sudden inventory report, a 20-tick stop might be too tight. You might need a 40-tick stop. If your max risk is $50, and the tick value is $7 (approx), a 40-tick stop costs $280. You cannot trade this. You must either wait for a clearer entry with a tighter technical stop or skip the trade entirely. This discipline is what protects your evaluation account.

The Tilt Factor: Recognizing When to Walk Away

Even with perfect math, human psychology is the biggest threat to the 2% cap. Tilt happens when you start trying to "make back" a loss. You take a loss, feel angry, and immediately enter a new trade with a larger position size to recover quickly. This is how accounts die.

Implement a Hard Stop Rule. If you lose 1% of your account in a single day, stop trading for the day. Do not try to get back to break-even. Do not try to make a profit. Close the platform.

Why 1%? Because if you lose 1%, you still have 1% of your daily loss buffer left. If you continue trading, you are likely to breach the 2% cap due to emotional decision-making. By stopping at 1%, you preserve the account for the next day. Surviving the evaluation is not about making 10% in a day; it is about not losing 2% in a day. Consistency beats intensity.

Practical Application: A Checklist for Every Trade

Before you click "Buy" or "Sell" on a China futures evaluation, run through this checklist. If you cannot check every box, do not take the trade.

• 1. Have I calculated my max dollar risk? (e.g., $50 per trade)
• 2. What is the tick value of the contract? (e.g., Rebar = 10 CNY/tick)
• 3. What is my stop loss in ticks? (Based on technical structure, not just a number)
• 4. What is the total risk in dollars? (Stop Loss Ticks x Tick Value x Lots)
• 5. Is the total risk below my max dollar risk? If no, reduce lots or widen account.
• 6. Am I already down 1% today? If yes, stop trading.
• 7. Is the market liquid? Avoid illiquid months (e.g., far-out expiries) where slippage can eat your margin.

This checklist removes emotion. It turns trading into a series of logical decisions. When you are in the heat of the moment, the checklist is your anchor.

Why This Discipline Transfers to Real Trading

Some traders view the 2% cap as an artificial constraint that doesn't exist in "real" trading. This is a dangerous misconception. Professional traders manage risk tightly. The 2% cap simply forces you to adopt professional habits earlier. If you can consistently follow this risk framework in an evaluation, you are already managing risk better than 90% of retail traders.

Furthermore, the skills you learn here—calculating tick values, respecting ATR, and enforcing hard stops—are directly applicable when you start to trade rebar or iron ore futures with real capital. The market does not care about your feelings; it only respects your risk management.

Surviving the evaluation is not about finding the perfect indicator. It is about surviving the day. It is about realizing that one bad trade should not end your career. It is about respecting the leverage of Chinese commodity futures and the strictness of evaluation rules.
