bitflyerでとりあえず前の1時間よりも安かったら買うプログラム

おもったより簡単にできた。

SBI銀行から毎日定額送金+下記をcronで回せばビットコン積立みたいなことができそうですね

工夫は後ほどやってみる

puts result

if (result['status'] == -201) then
puts ' ' + product_code + ' ' + buy_sell + " You have reached the maximum amount of trades for your account class."
return false
end

end

# 今の価格と1時間平均を比べる
url = URI.parse("https://www.bitstamp.net/api/ticker_hour/")
json = Net::HTTP.get(url)
result = JSON.parse(json)
now_price = result['last'].to_f
last_hour = result['open'].to_f

if now_price < last_hour then
order("BTC_JPY", "BUY", 0.001)
end
