A Short-Side Martingale Strategy with Doubled Re-Entries

Summary

This short-only strategy opens an initial sell position and monitors the ticker's buy price. If price falls far enough below the stored entry price to meet the take-profit threshold, it buys back the held amount and resets the position and doubling counter. If price rises past the stop-loss threshold and the configured doubling limit has not been reached, it buys back the current amount and opens a new short position at twice that amount.

The parameters specify a first order size, take-profit and stop-loss distances, and a cap on the number of doubling steps. The code reports the current position and step count, but supplies no backtest results or evidence of profitability. Because losses can prompt progressively larger exposure, the capped number of additions does not remove the risk of substantial losses, margin pressure, or adverse execution; fees and price gaps can also affect the thresholds in practice.

Key ideas

• The system begins with a short position of configurable size and tracks its entry price and amount.
• A favorable price move triggers a buyback and resets the position and doubling count.
• An adverse move triggers a buyback followed by a new short position at twice the prior amount, subject to a configured cap.
• The strategy specifies threshold distances and a maximum doubling count but provides no performance evidence.
• Repeatedly increasing short exposure can magnify losses and create margin and execution risks.
