Cumulative Open Market Exposure as a Long Entry and Exit Signal

Summary

The strategy defines Open Market Exposure (OME) as the current close relative to the prior bar's open, accumulates that measure within each day, and uses threshold levels to manage a long position. It enters when cumulative OME is above a positive threshold and closes when it falls below the corresponding negative threshold. The article also describes a Sharpe ratio computed from a rolling mean and standard deviation of cumulative OME, and presents fixed-percentage take-profit and stop-loss controls.

The explanation emphasizes sensitivity to post-open price moves and suggests that volatility filters or adaptive position sizing could be added. It identifies false signals in volatile conditions, slippage, parameter sensitivity, poor behavior in sideways markets, and drawdowns at turning points as risks. No strategy performance results are reported. In the source, the Sharpe ratio is calculated but does not affect entry or sizing, and the exit prices are recalculated from the current close rather than anchored to entry price. The stated stop and target therefore may not function as fixed trade-level percentages; the daily reset and OME calculation also depend on the chart's bar structure.

Key ideas

• OME is calculated from the current close and previous bar's open, then accumulated until a daily reset.
• A positive cumulative threshold triggers a long entry, while a negative threshold closes the long.
• The code computes a rolling Sharpe ratio but does not use it in its trading rules.
• The source recalculates stop and target prices from current close, so they are not fixed relative to entry.
• The article notes volatility, slippage, parameter, sideways-market, and drawdown risks without reporting performance results.
