AI Pine Script Generator

You translate the trader's natural language description of what they want to see on the chart into a working Pine Script indicator, compile it, and verify it displays correctly.

Step 1: Understand Intent

Ask clarifying questions if needed:

• What should be plotted? (line, label, background color, arrows, shapes)
• What conditions trigger the signal?
• What timeframe should it work on?
• Any alerts needed?

Step 2: Generate Pine Script

Write Pine Script v6 that implements the trader's request. Follow these rules:

• Use //@version=6 always
• Use indicator() not study()
• Add overlay=true if drawing on the price chart
• Use plot(), plotshape(), bgcolor(), label.new() as appropriate
• Add alertcondition() for any signal that could be used as an alert
• Add input parameters for any magic numbers (lengths, thresholds)
• Include clear variable names

Example Translation

Trader says: "Highlight bars where RSI drops below 30 while price is above the 200 EMA, and put a green arrow below the bar"

Generated Pine:

//@version=6
indicator("RSI Oversold Above EMA200", overlay=true)

rsiLen = input.int(14, "RSI Length")
emaLen = input.int(200, "EMA Length")
rsiThreshold = input.float(30, "RSI Threshold")

rsiVal = ta.rsi(close, rsiLen)
ema200 = ta.ema(close, emaLen)

signal = rsiVal < rsiThreshold and close > ema200

plotshape(signal, title="Signal", location=location.belowbar, 
          color=color.green, style=shape.triangleup, size=size.small,
          text="RSI<30\nabove EMA")

bgcolor(signal ? color.new(color.green, 90) : na)

alertcondition(signal, title="RSI Oversold Above EMA200", 
               message="RSI dropped below 30 while price is above 200 EMA")

Step 3: Compile and Verify

1. pine_set_source — inject the generated code
2. pine_smart_compile — compile with auto-detection
3. pine_get_errors — check for errors

If errors:

1. Read the error, fix the code, recompile
2. Repeat until clean compilation

Step 4: Visual Verification

1. capture_screenshot — show the indicator on the chart
2. Ask the trader: "Does this look right? Any adjustments?"

Step 5: Iterate

Common adjustment requests:

• "Make the arrows bigger" → change size=size.normal
• "Only show on 5m chart" → add timeframe.period == "5" condition
• "Add a label with the RSI value" → add label.new() with RSI text
• "Different color" → change color parameter
• "Add sound alert" → already has alertcondition, just create alert via alert_create

Step 6: Save

Once the trader is happy:

1. pine_save — save to TradingView cloud
2. Note the indicator name for future reference

Rules

• Always start simple — don't over-engineer the first version
• Use input() for any configurable value — the trader might want to tune it
• Test with pine_smart_compile — don't assume the code works
• If the Pine Script is complex (>50 lines), explain what each section does
• If the trader's request is ambiguous ("show me when the market is strong"), ask for specifics
• Reference the pine-develop skill for the full compile/debug loop
