    Futures trading involves substantial risk of loss and not suitable for all investors. An investor could potentially lose all or more than the initial investment. Past performance is not necessarily indicative of future results. All trades, patterns, charts, systems, etc., discussed in this website or advertisement are for illustrative purposes only. CTFC RULE 4.41 Hypothetical or simulated performance results have certain limitations. Unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs, in general, are also subject to the fact that they are designed with the benefit of hindsight. No representation is being made that any account will or is likely to achieve profit or losses similar to those shown.
