Periodic Fixed-Amount Buying with Threshold-Based Position Sales

Summary

The document describes a dollar-cost averaging approach: invest a fixed cash amount at regular intervals, accumulate units, and sell the position after it reaches a chosen size before restarting the cycle. It presents this as a way to build a long-term holding without needing to time every purchase. The stated example uses recurring purchases and a position threshold, but these are illustrative settings rather than evidence of performance.

The text argues that regular buying can moderate average entry cost and reduce the temptation to chase prices. It also warns that the method needs a long holding period, can lose money during prolonged declines, and depends on exit timing. No measured returns or comparative backtest results are provided. The accompanying script makes repeated fixed-dollar purchases, but its sale logic is commented out apart from a final position close; it therefore does not implement the full recurring sell-and-restart cycle described in the prose. The strategy also does not specify a market regime filter or a detailed exit rule.

Key ideas

• The strategy buys a fixed cash amount at regular intervals to accumulate an asset position.
• The described cycle sells the accumulated position after it reaches a preset size, then resumes periodic buying.
• Regular contributions can reduce reliance on choosing a single entry point, but they do not prevent losses in a prolonged decline.
• The method requires a long holding horizon and a deliberate exit plan.
• The included script does not implement the full threshold-based sell-and-restart cycle described in the text.
