Today I took some time to sort out the trading issues I've had with QQQ 0DTE expiration day options. It's also a way to do a periodic review and reminder for myself.

I currently only trade QQQ expiration day options. After reviewing, the most fatal and recurring problems are concentrated in four areas:

Selling too early: The entry point isn't actually bad, but when volatility spikes, I can't hold on, taking small profits and running, then watching the price surge later, too afraid to re-enter.

Holding on stubbornly in the wrong direction: Clearly, the judgment is already wrong, but I always want to wait for a rebound to break even before exiting, resulting in becoming more passive the longer I hold, and losses getting larger.

Making random spreads: Frequently trading small waves in choppy markets, trying to make some price difference, only to have the profits basically handed over as commissions.

Falling into entry point traps: Always buying at the halfway point, unable to withstand a pullback, and finally cutting losses at a relatively low point.

I now mainly use three indicators—QQQ volume, KDJ, and MACD—to determine direction and entry timing. I've also slowly summarized a few basic rules for my own use:

Must-check data before market open: Nasdaq futures trend, QQQ pre-market quotes, and whether there are major data releases like CPI, unemployment claims, etc.

Mark key levels in advance: The previous day's low as support, the previous day's high as resistance.

Determine direction: Bias towards Calls if futures are strong, bias towards Puts if futures are weak, and simply avoid choppy markets.

Indicator filtering: For RSI overbought (>75), wait for a pullback to the 60-70 range before considering entry; for oversold (<25), wait for a bounce to the 30-40 range before taking action, trying to avoid extreme market conditions.

Key questions for buying QQQ 0DTE: How to judge direction? How to find the best entry point? What are the sell signals? How to withstand volatility and avoid being shaken out? How to set exit discipline?
