Methodology

How our data & indicators work

Trust starts with transparency. This page explains exactly where TrendiView’s market data comes from, how often we refresh it, how each indicator is calculated, and — just as importantly — where the limits are.

Where our data comes from

We aggregate data from established, widely-used market data providers rather than generating our own prices. Each asset class draws from the sources best suited to it:

Cryptocurrencies

CoinGecko (prices, market cap, volume) · Binance (OHLC candles)

Spot prices, market capitalization, 24-hour volume and percentage changes are drawn from CoinGecko’s public market data. Candlestick (OHLC) history used for charts and indicators comes from Binance klines.

Stocks & ETFs

Yahoo Finance (chart API)

Quotes, previous-close comparisons and historical candles for equities and ETFs are sourced from Yahoo Finance’s chart endpoints. Prices reflect exchange data and may be delayed.

Gold, metals & commodities

Yahoo Finance (futures)

Gold, silver, platinum, palladium and commodities such as crude oil, natural gas and copper are priced from the relevant Yahoo Finance futures symbols (e.g. GC=F for gold).

Provider names are the property of their respective owners and are referenced here purely to disclose our sources. TrendiView is independent and not affiliated with, endorsed by, or sponsored by any data provider.

How often data updates

~60s

Live quotes

Prices and 24h changes are cached briefly (around a minute) to stay fresh while respecting provider rate limits.

Daily

Candles & indicators

Chart history and indicator values are built from daily OHLC candles and recomputed as new data arrives.

24/7

Crypto vs markets

Crypto trades around the clock; stocks and metals follow their exchange hours, so those quotes pause when markets are closed.

How we calculate indicators

Technical indicators are computed from OHLC candles using standard, widely-documented formulas and conventional default settings. We do not tune parameters to make the past look good — the defaults below are the industry-standard ones.

RSI — Relative Strength Index

Default 14 periods

A momentum oscillator scored 0–100. We compute the average of recent gains and the average of recent losses over the lookback window, form the relative strength (avg gain ÷ avg loss), and convert it to the 0–100 scale. Readings above 70 are conventionally “overbought” and below 30 “oversold” — conditions, not signals to act on.

Moving Averages — SMA & EMA

Common windows: 20, 50, 200

The Simple Moving Average (SMA) is the arithmetic mean of closing prices over the window. The Exponential Moving Average (EMA) weights recent prices more heavily so it reacts faster. Both are used to smooth price and gauge trend direction and dynamic support/resistance.

MACD — Moving Average Convergence Divergence

12 / 26 / 9 default

The MACD line is the difference between a 12-period and a 26-period EMA; a 9-period EMA of that line forms the signal line, and the gap between them is the histogram. It is used to read momentum shifts and trend changes.

Accuracy & limitations

We work hard to present data faithfully, but no market data platform is perfect, and honesty about that matters more than a false sense of precision. Please keep the following in mind:

  • Prices may be delayed or differ from your broker. Depending on the source and asset, quotes can lag real-time and will not exactly match the price at your specific exchange or broker.
  • Third-party data can contain errors or gaps. We depend on external providers; outages, corrections or anomalies on their end can flow through to what you see here.
  • Indicators describe the past, not the future. RSI, moving averages and MACD are all derived from historical price. They summarize what has happened; they cannot predict what will.
  • Nothing here is a recommendation. Data and indicators are tools for your own analysis, not signals to buy or sell.

Our editorial standards

Educational guides in our Learn hub are written and reviewed in-house by TrendiView Research. We hold every article to a simple rule: explain concepts honestly, avoid hype and “guaranteed return” language, and never present speculation as fact. When a topic is genuinely uncertain — as most of markets are — we say so plainly rather than pretending otherwise.
