Simulating Multicurrency Prices to Study a Rebuy Strategy

Summary

The article argues that limited market history can leave a trading system exposed to only one realized path, then proposes generating synthetic price series to examine a rebuy algorithm across many independent instruments. Its price model uses discrete steps, adjustable volatility, and probabilities for upward or downward moves. A parameter for average rollback controls how strongly prices tend to reverse after a move, allowing the simulation to vary the market’s flatness. The author suggests that this framework can also estimate trading-cycle duration and annualized profitability.

The practical section describes a multicurrency test EA and uses its results to argue that diversification can help the rebuy approach survive varied simulated paths. The author acknowledges that synthetic prices are not actual quotes and that the demonstrated algorithm still has an undesirable profit curve and requires a large initial deposit. The excerpts do not provide the complete equations, test settings, or evidence needed to validate the asserted long-term survivability, so the simulation should be treated as exploratory rather than proof of live-market robustness.

Key ideas

• The proposed simulation generates independent synthetic instruments to explore paths absent from limited historical data.
• Discrete price steps use volatility and directional probabilities to shape the simulated series.
• An average rollback parameter controls the degree of price reversal and market flatness.
• The author presents diversification as useful for studying the rebuy method across many simulated instruments.
• Synthetic prices and the reported EA results do not establish real-market performance, and the demonstrated approach has substantial capital demands.
