Question 1

How are the Buy/Sell signals calculated?

Accepted Answer

Each signal is derived from a set of widely used technical indicators computed on the stock's market prices. Moving averages (simple and exponential, across the 10, 20, 50, 100 and 200 periods) determine the trend component, while oscillators such as RSI, MACD, Stochastic and CCI measure momentum. Every indicator votes Buy, Sell or Neutral based on its own standard rules. The overall signal aggregates these votes: the more indicators agree, the stronger the overall rating — from Strong Sell through Neutral to Strong Buy. Signals are recalculated from the latest available candles, so the page always reflects the current technical picture for the selected timeframe.

Question 2

How often do signals update?

Accepted Answer

Signals are recomputed from the latest price data and cached for a short period. The "Updated" indicator above the gauges shows exactly how fresh the data you are viewing is. When the market is closed, the gauges keep showing the last completed session's signals and the indicator states the time they were computed.

Question 3

Do the signals include pre-market and after-hours trading?

Accepted Answer

No. All indicators are computed on regular trading hours candles only (9:30 a.m. to 4:00 p.m. ET). Extended-hours prices are typically thin and can produce distorted indicator readings, so they are excluded. The quote header on this page may therefore show a pre-market or after-hours price while the signals below still reflect the last regular session — the freshness indicator above the gauges states which session the analysis covers.

Question 4

What are pivot points?

Accepted Answer

Pivot points are price levels calculated from the previous period's high, low and close. Traders use them as potential support and resistance zones: prices trading above the pivot are considered bullish, below it bearish. We provide five common calculation methods — Classic, Fibonacci, Camarilla, Woodie and DeMark — each producing slightly different levels. Many traders combine pivot levels with the indicator signals above to plan entries and exits.

Question 5

Which timeframe should I use?

Accepted Answer

It depends on your trading horizon. Day traders typically focus on the short timeframes (15min and 30min), swing traders on 1H and 4H, and position traders and investors on the daily (1D) and weekly (1W) views. Signals on different timeframes can disagree — a stock can be bullish on the daily chart while short-term momentum is bearish. Checking that several timeframes align is a common way to increase confidence in a setup.

Question 6

What price data is the analysis based on?

Accepted Answer

The analysis is computed on consolidated US exchange prices — the same market data that powers the charts and quotes elsewhere on this page. Technical analysis is only offered for stocks with a sufficiently deep and actively traded price history, so signals are always based on a meaningful sample of candles.
