The narrow range inside day breakout strategy identifies narrow range oscillations and inside day close breakouts for long-only trend following. It generates long signals when price narrowing, inside day, and SMA slope up all emerge to capture post-breakout trends.
Use NR7 to identify the narrowest range day among the past 7 days.
Use inside day to determine previous day’s high is lower than current day’s high, and previous day’s low is higher than current day’s low.
When NR7 and inside day occur together, with closing price higher than opening price, go long.
Exit when next day’s close is higher than open.
The strategy utilizes both price narrowing and inside day signals to identify accumulation stages. With SMA slope up, price is likely to breakout. Such multi-condition filtering improves accuracy.
Also, the long-only approach avoids consolidation traps and unnecessary trades.
Considers both narrowing and inside day signals
SMA direction determines trend existence
Multi-condition filtering improves signal accuracy
Long-only avoids consolidation traps
Optimizable backtest parameters, flexible
SMA tuning needed to optimize signals
Long entry may lag, focus on breakout timing
Unable to profit from downtrends
Prevent re-expansion of ranges
The narrow range inside day breakout strategy thoroughly examines market structure and generates high-probability signals. With parameter tuning, it is highly adaptive. The strategy is worth backtesting, live optimization, and integration into overall quant systems.

// ChartArt's Narrow Range + Inside Day Strategy (Long Only)
//
// Version 1.0
// Idea by ChartArt on Oktober 16, 2016.
//
// This long only strategy determines when there is both
// a NR7 (narrow range 7, a trading day in which the range
// is narrower than any of the previous six days), plus a
// inside day (high of the current day is lower than the high
// of the previous day and the low of the current day is higher
// than the low of the previous day) both on the same trading day
// and enters a long trade when the close is larger than the
// open and the slope of the simple moving average is upwards, too.
//
// The strategy exits the long trade next time the close is
// larger than the open in any of the next trading days.
//
// In addition the NR7ID can be colored (if close large open
// colored in green, else in red) and the SMA can be drawn
// with a color based on the direction of the SMA slope.
