Using a Five-Day Index Drop as a Portfolio Risk Exit

Summary

This article describes a market-level risk control for an equity strategy. It calculates the five-day cumulative return of the Shanghai Composite Index and uses that reading as a benchmark risk signal. If the index return falls below negative four percent, the strategy is instructed to liquidate all holdings and stop processing trades for that day. The signal is prepared over the backtest or simulation date range, stored in the strategy context, and checked at the start of the main trading function.

The source explains the workflow in terms of a visual strategy template and its data preparation and main-function modules. It gives no backtest results, comparison, or evidence that the threshold improves returns or reduces drawdowns. The article also states that its instructions are outdated for the platform's current version. The approach is a simple broad-market overlay; its usefulness depends on the index matching the portfolio and on how the signal, selling costs, and trading timing are implemented.

Key ideas

• The risk overlay monitors the Shanghai Composite Index rather than only the strategy's individual holdings.
• A five-day index return below negative four percent triggers liquidation of all positions.
• The benchmark signal is prepared in advance and checked before the day's other trading logic.
• The article provides no performance evidence and says its platform instructions are outdated.
