Integration – Manually

You can calculate TA off of any candle set you have. Using this method requires sending a simple post including the candle data for which to calculate an indicator value.

Pro’s

• Calculate TA for any market / exchange / symbol / time frame, stock-market, crypto-market, OTC, etc… 
• Run backtesting on your strategy if you have the historical data.

Con’s

• You need to have / get the candle data ready yourself.

Getting started

Simply post your candles, along with your API Secret to the API:

[POST] https://api.taapi.io/rsi

Include a post parameter: ‘candles’ containing the candles in JSON. The candles must be sent as objects with below keys in an array:

• timestamp: An integer containing the timestamp of the candle in microseconds (not milliseconds)
• open: A float, containing the open price of the candle
• high: A float, containing the high price of the candle
• low: A float, containing the low price of the candle
• close: A float, containing the close price of the candle
• volume: A float, containing the volume of the candle

Example:

[
   {
      'timestamp': 83293829,
      'open': 238.32,
      'high': 343.12,
      'low': 125.94,
      'close': 243.48,
      'volume': 84342.84823
   },
   {
      'timestamp': 83293829,
      'open': 238.32,
      'high': 343.12,
      'low': 125.94,
      'close': 243.48,
      'volume': 84342.84823
   },
   ... n candles
]

The amount of candles depends on which indicator is used. If not sure, then send 300 candles. This amount will work for more or less all indicators.

Mandatory Parameters

Below a list of mandatory post parameters, needed to query the API “manually”:

Parameter	Type	Description
secret	String	The secret which is emailed to you when you Request an API key.
candles	JSON (array with candle objects)	A JSON encoded array of objects containing candle information (as described above)

Optional Parameters

There are no optional paramters for this integration method, other than the ones stated for each indicator on the Indicator endpoints page.

Note: You cannot use the ‘backtrack’ option with this method. If you need to calculate back in time, then remove candles from your dataset yourself.

Examples

NodeJS

// Require axios: npm i axios
const axios = require('axios');

axios.post('https://api.taapi.io/rsi', { // Replace rsi with any other indicator
  params: {
    secret: MY_SECRET,
    candles: [{...}]
  }
})
.then(function (response) {
  console.log(response.data);
})
.catch(function (error) {
  console.log(error);
});

PHP

<?php

$candles = [{...}]; // Candles json encoded
 
// Prepare new cURL resource
$ch = curl_init('https://api.taapi.io/rsi');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $canldes);
 
// Set HTTP Header for POST request 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($canldes))
);
 
// Submit the POST request
$result = curl_exec($ch);
 
// Close cURL session handle
curl_close($ch);

// View result
print_r(json_decode($result));
