Reference principal: 1000U (all position sizing ratios are based on this; when account funds change, positions are adjusted proportionally)

1. Perpetual Contract Trading Rules

1. Trading mode: use only the isolated margin (per-position) mode throughout

Original intention: isolate risk per single order. Even if this position loses or gets liquidated, only the margin for this position is lost, preserving the remaining principal in the account. This also prevents emotion from getting out of control in full-position mode, avoids manually loosening stop-losses, and prevents large losses or even liquidation of the entire account.

2. Leverage limit: maximum 3x leverage; do not blindly max out leverage.

3. Base position: The initial opening uses one-tenth of the principal. For example, with 1000U as the reference, the first position would be 100U. Subsequent position sizes are recalculated using the same proportion as funds change; do not arbitrarily increase the position size subjectively.

4. Averaging-in rules: For a single order, averaging in is allowed at most 1 time. After a loss, it is forbidden to increase position size to gamble for a recovery.

5. Order placement process: Enter the market first and place the order → after opening is completed, set the stop-loss level first → then set the take-profit level

II. Event contract trading rules

1. Trading cycle: try to trade event contracts with short timeframes only

2. Three-tier fixed positions: choose based on market certainty; do not arbitrarily add size:

- Small position: 1% of principal. Use it when market conditions are choppy/unclear and conviction is low

- Medium position: 2% of principal. Use when market signals meet the criteria and certainty is moderate

- Large position: 3% of principal. Use only for highly certain market scenarios. Prohibit using large positions after consecutive losses

3. Averaging-in rules: For the same order, you may average in at most 1 time. Never double up to recover losses.

III. Global risk-control ironclaws (mandatory enforcement for all trades)

1. For all instruments: after a loss, it is strictly forbidden to add to the position or increase exposure to try to break even. For each order, the maximum averaging-in limit is 1 time.

2. Daily risk control rule: when the total loss of all trades on the account (perpetual contracts + event contracts) reaches 10% of the principal, immediately stop all trading for the day and do not place any new orders.

3. Unemotional trading: strictly follow the position-sizing ratios you have set. Do not temporarily raise your bet size based on subjective judgment.
