Understand EMA, SMA, VWAP, and volume
An indicator transforms past prices or volume. It simplifies information and necessarily loses detail. OpenTrend metrics are optional so you can compare raw reading with assisted reading.
Fast and slow averages
EMA 9 reacts quickly, EMA 21 smooths more noise, and SMA 50 describes broader context.
Order and slope can describe dynamics, but a crossover often happens after movement begins.
VWAP and price acceptance
VWAP weights prices by period volume. Frequent returns around it suggest temporary balance.
Distance may mean acceleration or excess. The line alone cannot decide between them.
Volume confirms activity, not direction
A spike means more activity accompanies the candle. Observe what price does afterward.
A high-volume break that immediately returns tells a different story from several continuing closes.
Price moves above EMAs with volume while SMA remains flat. Short dynamics accelerate, but slow context is not aligned yet.
Common mistakes
- Enabling every metric until price is hidden.
- Buying or selling on every crossover.
- Reading a volume spike as a certain direction.
Read a metric
- 1 What does it actually measure?
- 2 Does it confirm price or tell a different story?
- 3 Would the decision remain defensible without the line?
Quick questions
Which metric is best?
None works in every context. Start with one metric linked to your question.
Why do lines lag?
Because they are calculated from closes that are already known.
Technical indicators use historical data and guarantee no future return.
