That is arithmetically possible. It does not establish that an advertised trade actually occurred, that the entire account multiplied, or that the result can be repeated without taking a large risk of loss. The same amplification works against a position.","波动较大的资产与杠杆仓位，可能让一小笔占用保证金出现很高的百分比收益，算术上并非不可能。但这不能证明宣传中的交易确实发生、整个账户翻了几倍，或该结果能在不承担巨大损失风险的情况下重复。放大作用也会反向作用于仓位。"],["A screenshot without a complete record is insufficient evidence, rather than automatic proof of fraud. Fabrication, a genuine lucky trade and selective disclosure can look similar from outside. An assessment should distinguish an unsupported claim from a demonstrated falsehood.","缺少完整记录的截图属于证据不足，不能自动认定为诈骗。伪造、真实的幸运交易与选择性披露，从外部看可能很相似。判断时应区分未经支持的主张与已经证实的虚假陈述。"]]},{"heading":["First ask what the percentage divides by","先弄清百分比的分母"],"paragraphs":[["A position-level return may divide profit by the margin allocated to that position. An account-level return concerns all capital supporting the activity, including idle cash and collateral elsewhere. A large percentage on one small position may coexist with a modest or negative account result. The platform’s return definition should be read before comparing figures.","仓位收益可能用利润除以分配给该仓位的保证金；账户收益则涉及支撑交易活动的全部资本，包括闲置现金和其他位置的抵押品。小仓位的大百分比收益，可能与全账户微利甚至亏损同时存在。比较数字前，应先阅读平台的收益定义。"],["Account equity includes both cash and the marked value of open positions. Realised gains alone can hide unrealised losses. Deposits, withdrawals and transfers must be reconciled before estimating investment returns; when capital enters at different times, a simple ending-balance ratio is not enough. A consistent cash-flow-adjusted method is needed.","账户权益包含现金与未平仓头寸的盯市价值，仅展示已实现利润可能隐藏浮亏。估计投资收益前，应核对充值、提现与转账；如果资金在不同时间进入，仅比较期初期末余额并不充分，需要一致的现金流调整方法。"]]},{"heading":["Selection can make genuine results misleading","真实结果也可能因筛选而误导"],"paragraphs":[["Showing the best trade while omitting losses changes the question from “does this process earn money?” to “did at least one attempt succeed?” The same problem appears when a promoter runs several accounts but publicises only the survivor. A long record is more informative when it includes every account, discontinued attempt, drawdown and open position under a consistent scope.","展示最佳交易却省略亏损，会把“整个过程是否赚钱”偷换成“是否至少有一次成功”。同时运营多个账户却只宣传幸存者，也存在同样问题。较长记录只有在范围一致、包含全部账户、终止尝试、回撤与未平仓头寸时，才更有解释力。"],["A win rate is not a profitability measure on its own: the sizes of wins and losses matter. Nor does a short favourable streak establish skill. The assessment needs net results, exposure, the size and duration of losses, and performance across different market conditions. No private trading signal is needed to disclose these outcomes.","胜率本身不是盈利指标，单次盈利与亏损的幅度同样重要；短期顺利也不能证明能力。评估应关注净结果、风险敞口、损失幅度与持续时间，以及不同市场环境下的表现。披露这些结果无需公开私人交易信号。"]]},{"heading":["Separate research, simulation and live execution","区分研究、模拟与真实执行"],"paragraphs":[["A backtest can use unavailable information, pick favourable settings after seeing the result, or assume fills that a real order would not receive. A demo account tests some operational behaviour but does not reproduce every live execution constraint. Live records should include fees, funding, spread and rejected or partially filled orders. These are evidence requirements, not a trading recipe.","回测可能使用当时不可得的信息、看过结果后挑选有利设置，或假设真实订单无法得到的成交。模拟账户能够检查部分运行行为，却不能复现所有真实成交约束。实盘记录应包含手续费、资金费、价差，以及拒单和部分成交。这些是证据要求，不是交易方法。"],["Revenue from courses, subscriptions, referral commissions or copy-trading fees should be separated from trading profit. Those business models can exist alongside genuine trading, but they create incentives that a viewer should understand. Promises of guaranteed profits are a warning sign highlighted by the CFTC; a guarantee is not a substitute for an auditable record.","课程、订阅、返佣和跟单服务费收入应与交易利润分开。这些商业模式可以与真实交易并存，但读者应理解其中的激励。CFTC 将保证盈利的说法列为风险信号，保证不能替代可审计的记录。"]]},{"heading":["What published research can and cannot tell us","外部研究能说明什么"],"paragraphs":[["The authors of Day trading for a living? report that 97% of the Brazilian equity-futures entrants from 2013–2015 in their cohort who persisted for at least 300 days lost money.
