K棒開盤突破箭頭（4小時邏輯 + 可調距離）

This indicator plots visual arrow signals based on specific opening breakout conditions.

🟢 A green upward arrow appears above the bar when:

The current bar’s opening price is greater than the previous bar’s close +10 points, and

The current bar’s open is also higher than the previous bar’s open

🔴 A red downward arrow appears below the bar when:

The current bar’s opening price is lower than the previous bar’s close −10 points, and

The current bar’s open is also lower than the previous bar’s open

These conditions are designed to detect strong opening gaps that suggest potential breakout moves. The indicator is non-repainting and suitable for use in manual signal tracking or alert setup.

Best used on:

Higher timeframes (e.g., 1H, 4H, Daily)

Indexes, futures, or assets with noticeable price gaps
