[アービトラージ] 取引所でサポートされている通貨ペアの列挙と組み合わせ

今日は、いきなりソースコードです。

指定した取引所でサポートされている通貨ペアとmaker,taker手数料（%）を列挙します。

// いつものccxt 
const ccxt = require('ccxt');
// 取引所IDを引数で受け取る
if(process.argv.length < 3) {
  console.log('実行時に取引所IDを引数で指定してください。 例： node ./checkexchange.js bitbank');
  process.exit();
}
const exchange = process.argv[2]; // 取引所ID

(async () => {
  const ex = new ccxt[exchange];
  const markets = await ex.loadMarkets();

  console.log(`◾◾◾ ${exchange} ◾◾◾`);
  console.log('symbol, base, quote, maker, taker');
  for(const key in markets) {
    const market = markets[key];    
    console.log(`${market.symbol}, ${market.base}, ${market.quote}, ${market.maker}, ${market.taker}`);
  }
})();

使い方はソースコード中にも書いていますが、実行時の引数にccxtの取引所IDを渡してあげるだけです。

試しにbitbankを指定してみましょう。

◾◾◾ bitbank ◾◾◾
symbol, base, quote, maker, taker
BCH/BTC, BCH, BTC, 0, 0
BCH/JPY, BCH, JPY, 0, 0
MONA/BTC, MONA, BTC, 0, 0
MONA/JPY, MONA, JPY, 0, 0
ETH/BTC, ETH, BTC, 0, 0
LTC/BTC, LTC, BTC, 0, 0
XRP/JPY, XRP, JPY, 0, 0
BTC/JPY, BTC, JPY, 0, 0x

のような結果が出力されました。
bitbankは手数料が無料のようですね。でも、あまり通貨ペアの数は無いようです。

次にliquidを試してみましょう。

ひゃー。非常に多くの通貨ペアが用意されているようです。
でもかなりの数の通貨ペアに売買手数料が設定されているのがわかります。

これだけの数があれば、取引所内取引で使えそうな通貨ペアの組み合わせがありそうです。

条件としては
・手数料が無料（別にあっても良いが、無い方が計算が楽）
・通貨ペアは最低３つ以上
・それぞれが連携して売買できること
ですかね。

例えば、まず最初に JPYでBTCを買っておきます。
（最初からBTCを持っていれば、送金でOK）

１.　BTCでETHを買う (ETH/BTC)
２.　ETHでONTを買う (ONT/ETH)
３.　ONTでBTCを買う→ONTを売ってBTCを得る (ONT/BTC)

って感じで繰り返せば言い訳ですよね。（たぶん）

１と２は結局BTCでONTを買っていることになり、3で売り払う数量は１と２で購入したONT数量と同じにすれば、ぐるぐる回せることになります。

ただし、売買タイミングによっては「当然損」なこともあるので、うまく「差益」が出るタイミングをずっと我慢して待つわけですね。

ざっと見た所、ONTをQASHという通貨に変えてもいけそうです。

次回以降でそんな「うまいタイミング」を見つけるプログラムを作っていこうと思います。
