Moving averages: the 8, 21, 50, and 200-week
A moving average smooths price into a trend line. Four of them do most of the work in this record: the daily 8 EMA, 21 EMA, 50 SMA, and the 200-week VWMA.
A moving average is the average closing price over the last N bars, redrawn every bar. It turns a noisy chart into a line that shows the direction and pace of the trend.
The three kinds used here
- SMA (simple): every bar counts equally.
- EMA (exponential): recent bars count more, so it turns faster. Good for short-term trend.
- VWMA (volume-weighted): bars with more volume count more. It shows where the most shares actually changed hands.
The four on every chart
| Average | Job |
|---|---|
| 8 EMA (daily) | Short-term trend. Pullback entries happen near it, and a daily close below it is my trailing exit on runners. |
| 21 EMA (daily) | Intermediate trend. Healthy uptrends stay above it. |
| 50 SMA (daily) | The longer trend most institutions watch. |
| 200-week VWMA | A very long-term value line, used for deep-value entries and targets. |
How they're used together
Stacked in order, with price above the 8, the 8 above the 21, and the 21 above the 50, is a healthy uptrend. The gap between the 21 and the 50 matters too: a thin gap means a sharp drop can flip the trend fast. That's the heart of the market regime filter.
Moving averages aren't support or resistance by magic. They're a consistent frame of reference, and that consistency is the point.

- Narrowing it down: a regime filter built on SPY and QQQAfter a hot CPI print pushed QQQ below its 21 EMA, I worked out a simple frame for when to take risk at all, and when to buy pullbacks.
- Risk came off: reading a broad risk-off daySeveral trailing positions stopped out on the same day. What the cross-asset picture said about why, and what it would take to get constructive again.

- Breakout from a baseA leading stock clears the top of a multi-week base on rising volume. Buy the break, stop under the breakout day, add only on a new base.
- Deep value: buying quality near the 200-week VWMAA quality company sells off to its 200-week volume-weighted average. Scale in at pre-set levels, then manage it like a pullback once the trend turns.
- Market regime filter (SPY & QQQ)Before buying individual stocks, check SPY and QQQ against their 8, 21, and 50-day averages. When they're below, stand down or only trade the indexes. When the 21 sits close above the 50, don't buy pullbacks.
- Pullback in an uptrendA strong stock dips back to its rising 8 EMA and holds. Buy the hold, stop under the day's low, trim into the next push.
- Squeeze: tight range, building momentumVolatility contracts into a tight range while momentum builds underneath. The entry is the break out of the coil, with a stop at the day's low.
- Trailing stop: the daily close below the 8 EMAAfter the first trims, the remainder rides until the stock closes a day below its 8 EMA. It's a rule that lets winners run without guessing the top.
