v3fixed the main issue with the indicator lines not showing properly. The problem was in how the bar indices were being calculated for drawing the lines.
🔧 Key Fixes Made:
1. Bar Index Calculation:
Before:

pinescriptbar_index[barIndex] + barIndexOffset

After:

pinescriptbar_index - barIndex + barIndexOffset

2. What Was Wrong:
The original code was using bar_index[barIndex] which tries to get a historical value of bar_index itself
This was causing incorrect X-coordinates for the lines, making them not visible or positioned incorrectly

3. What's Fixed Now:

MACD Lines: Blue MACD line and orange signal line will now draw properly
RSI Line: Purple RSI line will show correctly in the middle panel
Stochastic Lines: Blue %K and orange %D lines will display properly
Histogram: MACD histogram bars will appear correctly
Signals: Buy/sell signals will be positioned correctly

🎯Fix Works:
The corrected formula bar_index - barIndex + barIndexOffset properly calculates the X-coordinate by:

Taking the current bar index (bar_index)
Subtracting the historical offset (barIndex)
Adding the positioning offset (barIndexOffset)

This ensures the lines are drawn at the correct horizontal positions within the floating panels.
✅ Expected Results:
MACD Panel: Clear blue and orange lines with histogram bars
RSI Panel: Smooth purple RSI line oscillating between 0-100
Stochastic Panel: Blue %K and orange %D lines with overbought/oversold areas
