A Loss-Scaling Betting Strategy with Fixed Profit and Loss Thresholds

Article Strategy library · Author: 发明者量化-小小梦

Summary

This document presents a position-sizing scheme that starts with a small buy and doubles the next buy after price falls past a fixed loss threshold. The position is sold when price rises past a fixed profit threshold from the most recent recorded entry. Parameters include the initial order size, profit and loss distances, and a maximum number of doublings. The loop checks prices frequently and displays the current position and doubling count.

This resembles a loss-recovery betting progression: increasing exposure after adverse moves aims to recover losses with a subsequent rebound. The source gives no market rationale, backtest, or evidence that rebounds occur before capital or position limits are reached. Its behavior is especially constrained once the maximum doubling count is reached, because the shown logic has no further loss exit in that state. Fees, slippage, liquidity, price gaps, and the cumulative exposure from repeated increases can materially affect outcomes; fixed thresholds do not adapt to volatility. The method therefore illustrates a sizing rule, not a demonstrated trading edge.

Key ideas

  • The scheme begins with a buy and doubles order size after each specified adverse price move.
  • It sells the accumulated holding after a specified favorable move from the latest recorded entry.
  • A maximum doubling count limits the number of size increases, but the shown logic does not define a subsequent loss exit.
  • The document supplies no backtest or evidence that the price will rebound before exposure grows substantially.
  • Fees, slippage, gaps, and available capital affect the practical result.
