IPO Day High

IPO High plots a horizontal reference level at the high of a stock’s IPO day — but only if the company went public within a user-defined recent period (default: last 2 years).

This level often acts as a key psychological and technical reference for recently listed stocks, commonly used by traders to track:

Early supply zones

Price discovery rejections

Breakout continuation above IPO highs

Post-IPO consolidation structures

How It Works

The script detects the first available daily candle in TradingView’s historical data for the symbol.

That candle is treated as the IPO day.

It extracts the high price of that session.

If the IPO occurred within the last X years (user input), the script draws a horizontal line from the IPO date forward.

If the IPO is older than the selected lookback period, the line will not display.

Practical Use Cases

Traders commonly monitor IPO highs for:

Breakout confirmation

Failed breakout / bull trap detection

Support reclaim after pullbacks

Momentum continuation setups

Particularly useful for:
