Expected value equations expect you to trade every moment of the day and every opportunity you have. However, you have a choice.

1. You know the stock market usually* goes up

2. You know put credit spreads win when the market is flat or up

3. You understand bearish trades don't win as often as bullish trades

Then suddenly you can have an advantage if you trade long enough. You don't ALWAYS have to trade, especially volatile times like right now. You can afford to wait for an uptrend and then open a trade there where you have a higher chance of success.
