Contrarian Index Buying with Volatility Pauses and Staged Entries

Summary

The document describes a long-only index strategy that begins buying after a down bar, then adds to the position when price falls sufficiently below the last purchase and a short-term volatility measure signals a pause. It uses a near-zero profit threshold to close the accumulated position and attempts to re-enter on later pullbacks. Position size is tied to account capital and a margin estimate, while a flag prevents purchases on consecutive bars.

The author says the approach adapts a manual ETF method used since 2010 and shares example code and parameters, including a 12-hour timeframe. However, the document provides no performance results or rigorous backtest evidence. It raises unresolved questions about overnight financing on cash CFDs and rolling futures contracts. The strategy can accumulate exposure during persistent declines, and its sizing, volatility filter, transaction costs, financing, instrument choice, and roll handling all require careful evaluation before use.

Key ideas

• The strategy opens long positions after a down bar and adds when price declines beyond a set threshold.
• A short-term standard deviation comparison is used to identify a local pause in falling prices.
• A small profit threshold closes the full position, after which the strategy can seek another entry.
• Position size depends on account capital and an estimated margin amount, so assumptions affect exposure.
• The document gives no measured results and leaves financing costs and futures rollover unresolved.
