MA Slope Turn + OL/OH + 1m Spike (NR) — live

This indicator identifies trend reversals using moving average slope turns, with additional filters for price action (Open≈Low/Open≈High) and volume spikes. Here's how it works:
Core Logic
Moving Average Calculation:

Calculates selected MA type (SMA, WMA, RMA, HMA, Triangular)

Plots MA line colored by slope direction (green=up, red=down)

Slope Detection:

slope = current MA - previous MA

Valid turn requires:

Minimum slope magnitude (minSlope)

Slope direction change (positive→negative or negative→positive)

Additional Filters:

Open≈Low (BUY): (Open - Low) ≤ Tolerance% of Open

Open≈High (SELL): (High - Open) ≤ Tolerance% of Open

1m Volume Spike: Volume ≥ (SMA(volume) × Multiplier) in last N minutes
