What is a straddle chart?
A straddle is a call and a put of the same strike and expiry. A straddle chart plots their combined premium through the day. On ScreenerCharts it follows the at-the-money (ATM) strike, the one closest to the current price, so you see what the market is charging for a move right now.
How traders read it
- Falling straddle: premiums are decaying through time decay or falling volatility, which usually favours option sellers.
- Rising straddle: the market is moving or volatility is picking up, which usually favours option buyers.
- Straddle VWAP: each chart has the volume-weighted average premium. Trading above it often means buyers are in control; below it, sellers.
- Other expiries and past days: compare the weekly and the monthly straddle, or replay any of the last 30 days minute by minute.
- Strike Picker: follow a fixed straddle or a strangle on the strikes you hold instead of the ATM.
