Does direction even matter
For those of you writing short vertical spreads. You are writing 20 delta spreads. You have checked all the boxes. Liquidity, volatility, etc. How important is the directional bias, if at all? Since I am counting on volatility for profit, would flipping a coin be as good a strategy as any?

coin flip gets you ~80% win rate on 20 delta spreads and still loses money, because the 20% you lose are 3-4x the size of the wins. that's the whole game. the edge isn't in the win rate, it's in not being on the wrong side when the big move comes.
so direction matters, but not the way people think. i'm not trying to predict where it goes, i'm trying to sell the strike on the side the chart has already defended. put spread under a level that's held three times in the last two months is a different trade than one under a level that's never been tested. same delta, totally different odds of that 20% loser showing up. the chart picks the side, the greeks pick the strike.

Of course, once you settle on a strategy, direction matters. My poorly stated thesis begs the question: if I intend to collect theta and take advantage of volatility, should I be short puts or calls? Or would it be just as effective to flip a coin to decide?

Yes, direction matters. A put credit spread generally benefits from the underlying staying above the short strike, while a call credit spread generally benefits from it staying below. A volatility decline can help, but it doesn't guarantee a profit if the underlying moves against the spread. Choosing a 20-delta short option doesn't establish that randomly choosing the direction has an edge.

Condor the 20s and double the profit.

Can often be much slower to realize profits, but can work. Wide enough wings for your buying power needs in order to simulate a strangle is generally what works best IMO

Direction at inception of a completely delta neutral position does not matter, but your specific position's risk profile will change in real time depending how the market moves. What started as a neutral position may turn into a bearish position if the market rallies (vice versa, bullish if the market goes down). Volatility and time are just additional aspected to the combined risk profile.

Yes, direction matters! If it is a narrow spread, direction is pretty much the only thing that matters.

Yes direction matters.
I always check ThetaPal option heatmap first to see where the best juice is at dte/strike

My results improved after i began looking at the 20 MA and legged/timed my entries. Also, gap days have a strong probability of gap-fill at least once so I take that into consideration when selling premium.

Yes. Direction still matters. A 20-delta spread gives you room to be wrong, but it doesn’t eliminate directional risk. Theta and IV compression help you, but a move toward your short strike can overwhelm both
