cTrader Custom Indicator Update Compatibility Checklist

Open checklist

Trading risk disclosure

Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading, and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Hypothetical performance disclosure

Hypothetical performance results have many inherent limitations. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown. There are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. Hypothetical results are generally prepared with the benefit of hindsight, do not involve financial risk, and cannot completely account for the impact of financial risk in actual trading. Market conditions, the ability to withstand losses, and adherence to a trading program can all materially affect actual results.
