Find the event on the clock
If the event is dated, the expiry that contains it (or the one just after) is where implied move lives. Term inversion — front IV above back — is a common signature. If the event is vague (“sometime this quarter”), you are guessing both outcome and clock.
TradFi overlay desks on /t/{asset}/tradfi/calendar are research calendars, not a complete list of crypto-native risks.
Read the implied move
ATM straddle price (or IV-to-expiry conversion) is a rough width the market is willing to sell. If you buy the straddle, you need more realized than that width after costs, or a vol spike that lets you exit. If you sell it, you are saying the width is too fat.
See expected-move. This is a hurdle, not a forecast of direction.
IV crush is the other side of the event
After a binary print, front IV often falls even if spot moved — because uncertainty collapsed. Long premium that “needed a move” can lose on crush if the move was smaller than priced. Short premium can win on crush and still lose if the move was larger than priced.
Do not be surprised. Price both outcomes before the event, not after.
Structures people actually use (mechanics, not recos)
Long straddle/strangle: pay for a big move. Short iron condor: fade a too-wide implied. Calendar: fade the front rich vs back. Directional vertical: you have a side and want defined risk. Risk reversal: you think skew is wrong into the event.
Pick one. Mixing all of them is not a “complex book,” it is confusion.
Operational reality
Spreads widen into the print. Liquidations in perps leak into options via dealer hedges. Some venues thin out. If you cannot trade during the window, you do not have an event strategy — you have a hope.
Geo and KYC still apply. An event does not make a blocked venue available.

/t/btc/term, /t/btc/expected move via vol desks, /t/btc/iv-percentile, /t/btc/strategy. Calendar context on tradfi desks. Then /venue if you will actually trade the legs.
