The script language is composed of several rules composed of a currency pair and a mathematic expression.
|
|
The example below will use <code>kraken</code> for both <code>LTC_USD</code> and <code>BTC_USD</code> pairs.
|
|
</p>
|
|
<pre>
|
|
<code>
|
|
LTC_USD = kraken(LTC_USD);
|
|
BTC_USD = kraken(BTC_USD);
|
|
</code>
|
|
</pre>
|
|
<p>However, explicitely setting specific pairs like this can be a bit difficult. Instead, you can define a rule <code>X_X</code> which will match any currency pair. The following example will use <code>kraken</code> for getting the rate of any currency pair.</p>
|
|
<pre>
|
|
<code>
|
|
X_X = kraken(X_X);
|
|
</code>
|
|
</pre>
|
|
<p>However, <code>kraken</code> does not support the <code>BTC_CAD</code> pair. For this reason you can add a rule mapping all <code>X_CAD</code> to <code>ndax</code>, a Canadian exchange.</p>
|
|
<pre>
|
|
<code>
|
|
X_CAD = ndax(X_CAD);
|
|
X_X = kraken(X_X);
|
|
</code>
|
|
</pre>
|
|
<p>A given currency pair match the most specific rule. If two rules are matching and are as specific, the first rule will be chosen.</p>
|
|
<p>
|
|
But now, what if you want to support <code>DOGE</code>? The problem with <code>DOGE</code> is that most exchange do not have any pair for it. But <code>bittrex</code> has a <code>DOGE_BTC</code> pair. <br />
|
|
Luckily, the rule engine allow you to reference rules:
|
|
</p>
|
|
<pre>
|
|
<code>
|
|
DOGE_X = bittrex(DOGE_BTC) * BTC_X
|
|
X_CAD = ndax(X_CAD);
|
|
X_X = kraken(X_X);
|
|
</code>
|
|
</pre>
|
|
<p>
|
|
With <code>DOGE_USD</code> will be expanded to <code>bittrex(DOGE_BTC) * kraken(BTC_USD)</code>. And <code>DOGE_CAD</code> will be expanded to <code>bittrex(DOGE_BTC) * ndax(BTC_CAD)</code>. <br />
|
|
However, we advise you to write it that way to increase coverage so that <code>DOGE_BTC</code> is also supported:
|
|
</p>
|
|
<pre>
|
|
<code>
|
|
DOGE_X = DOGE_BTC * BTC_X
|
|
DOGE_BTC = bittrex(DOGE_BTC)
|
|
X_CAD = ndax(X_CAD);
|
|
X_X = kraken(X_X);
|
|
</code>
|
|
</pre>
|
|
<p>
|
|
It is worth noting that the inverses of those pairs are automatically supported as well.<br />
|
|
It means that the rule <code>USD_DOGE = 1 / DOGE_USD</code> implicitely exists.
