<p>I've looked at various websocket feeds from crpyto exchanges and they in general are like this</p>

<pre><code>{
  "jsonrpc": "2.0",
  "method": "ticker",
  "params": {
    "ask": "0.054464",
    "bid": "0.054463",
    "last": "0.054463",
    "open": "0.057133",
    "low": "0.053615",
    "high": "0.057559",
    "volume": "33068.346",
    "volumeQuote": "1832.687530809",
    "timestamp": "2017-10-19T15:45:44.941Z",
    "symbol": "ETHBTC"
  }
}
</code></pre>

<p>As i understand a ticket is a feed on every price change.. so sure enough the wss feed streams updates for the coin pair as the price changes.</p>

<p>What is not clear is what do the <code>open</code>, <code>high</code>, <code>low</code>, <code>last</code> fields represent ? The open of what ? Since the previous price change just milliseconds ago ? </p>

<p>Can someone explain wither from a polled REST feed or streamed websocket feed what these numbers are really referring to please given the gap bet between received data is so short ? </p>

As i understand a ticket is a feed on every price change.. so sure enough the wss feed streams updates for the coin pair as the price changes.

What is not clear is what do the `open`, `high`, `low`, `last` fields represent ? The open of what ? Since the previous price change just milliseconds ago ?

Can someone explain wither from a polled REST feed or streamed websocket feed what these numbers are really referring to please given the gap bet between received data is so short ?

**open** is the price at which a security first trades upon the opening of an exchange on a given trading day; for example, the New York Stock Exchange opens at precisely 9:30 a.m. Eastern.

**High** the highest value within 24 hours.

**Low** the lowest value of 24 hours.

**Last** as the price gets update upon live trades so, last is the last trade price. for example, if I've sold my bitcoins for 11,000 so last will be 11,000
