Mis à jour Accumulation/Distribution Line (Volume Surge Markers) - TP

This indicator plots a classic Accumulation/Distribution (A/D) Line, built manually from the candle’s close position and volume, then adds circle markers when volume spikes versus the previous bar.
What the A/D Line means (in plain English)
Think of each candle as a “battle” between buyers and sellers:
If the candle closes near the high, that bar is treated as buying pressure (accumulation).
If the candle closes near the low, that bar is treated as selling pressure (distribution).
If it closes near the middle, it’s more neutral.
The script converts that “close location” into a score from -1 to +1, multiplies it by volume, then cumulates it over time.
So the A/D line rises when “buying-style” bars dominate, and falls when “selling-style” bars dominate.
Volume Surge Circles
A circle prints when the current bar’s volume is at least 50% higher than the previous bar (default).
This helps you spot moments where participation suddenly increases and can confirm (or warn) about moves.
Best way to use it
This tool is most useful when you overlay it on the price chart (like in the screenshot), so you can quickly compare:
price trend vs A/D trend (divergences),
and where volume surges occur relative to breakouts, pullbacks, or reversals.
Tip: Watch for cases where price keeps rising but the A/D line goes flat or down — that can hint the move is losing real accumulation.

Notes de version
Updated the indicator to **overlay on the main price chart** by switching `overlay=true`, and added `scale=scale.none` so the A/D line **follows panning/zooming with the candles** without **distorting or affecting the chart’s price scale**.Notes de version
I took A/D line and made it more robust: I added a gap-aware version so big jumps don’t mess it up, added $-weighted versions so it reflects real dollars moving, and I now have 4 modes to choose from. I also updated the $-weight price source list to match TradingView’s options, and my volume-surge circle markers still work on whichever mode I pick.Notes de version
