RSI + Psy + ADX

RSI + Psychological Line + ADX (with RCI-replacement logic)

This custom TradingView indicator combines three major technical analysis tools—RSI, Psychological Line (Psy), and ADX—to help traders identify trend strength, market momentum, and overbought/oversold conditions with improved clarity.

1. Multi-Period RSI

The indicator calculates three RSI values:

Short-term RSI (9)

Mid-term RSI (26)

Long-term RSI (52)

These help users observe short-, mid-, and long-term momentum simultaneously.
Threshold lines are drawn at 70, 50, and 30 for standard RSI overbought/oversold analysis.

2. Psychological Line (Psy) with Dynamic Column Display

The Psy indicator counts how many closes within the selected period (default: 12) were higher than the previous close.

Values above 75 indicate overbought markets.

Values below 25 indicate oversold markets.

When Psy crosses these thresholds, it is displayed as a column chart centered at 50, visually expanding upward (overbought) or downward (oversold).

3. ADX Trend Strength with Color Coding

ADX is calculated from DI+ and DI− values (using true range and directional movement).
The ADX line changes color based on trend strength:

Blue: Weak trend (below 20)

Yellow: Moderate trend (20–30)

Red: Strong trend (above 30)

This helps traders easily recognize when the market transitions from low-volatility to strong-trend conditions.
