SMT for Dax correlation EU Stocks

I asked Chat GBT and it created something which has some errors. Here is the Code:

//==============================
// SMT Divergence: DAX vs SX5E
// Built for ProRealTime
//==============================

indicator(“SMT Divergence DAX vs SX5E”, overlay)

// — SETTINGS —
lookback = 10 // swing high/low length
symbolSX5E$ = “SX5E” // Adjust if your data uses another symbol like “EUSTX50”

// — SX5E price fetch —
priceSX5E = close(symbolSX5E$)

// — Swing High / Low Detection —
swingHighDAX = high = highest[1](high, lookback) AND high > highest[1](high, lookback)
swingLowDAX = low = lowest[1](low, lookback) AND low highest[1](priceSX5E, lookback)
swingLowSX5E = priceSX5E = lowest[1](priceSX5E, lookback) AND priceSX5E < lowest[1](priceSX5E, lookback)

// — SMT Conditions —
bullishSMT = swingLowDAX AND NOT swingLowSX5E
bearishSMT = swingHighDAX AND NOT swingHighSX5E

// — Plot —
if bullishSMT then
drawtext("🔵 SMT Bullish", barindex, low – AverageTrueRange[14], dialog, bold, 0, 255, 0)
drawarrowup(barindex, low – AverageTrueRange[14]*0.5, 0, 255, 0)
endif

if bearishSMT then
drawtext("🔴 SMT Bearish", barindex, high + AverageTrueRange[14], dialog, bold, 255, 0, 0)
drawarrowdown(barindex, high + AverageTrueRange[14]*0.5, 255, 0, 0)
endif

would really apprechiate if someone would create one.

thank you in advance,
