Is there a website or application which compares price differences across exchanges in real time?

For example 2 weeks ago we saw BCD hundreds of dollars higher on Bittrex or Kucoin (not sure which exchange it was) than it was on Binance leading to a massive increase in price over a day or so on Binance. Could have easily made some quick bucks if you were one of the first to realise.

So does anyone know of anything like this?

What you are talking about is called arbitrage. There are several people who use scripts for it, they have bots that compare prices between the various exchanges and make the right trades when the price difference between exchanges is worth it. I can't tell you where you can get those scripts, probably many script sellers will just try to scam you...

Thanks for the reply. Certainly a gap in the market for something like this.

Arbitrage is a hard game. Sometimes fees are more than what you will get. I saw some projects. One of them is called black bird. You can check here.

This is indeed an arbitrage way of trading which you are making money out of those spreads on coins between exchanges but these kind of scenarios do only see on less chances because most of the times exchanges do only have small spread but there are really times which it exceeds and giving out the opportunity to arbitrage but you should really be fast since these chances can really give you money if you done it right.

these opportunities are rarer and rarer;
markets are almost 100% aligned now
only exchanges with inexistant or very low volume show price differences

And this is something very difficult to do.. i still can not understand why everybody thinks that this is something new.
This is arbitrage guys! And it can not be done manually unless that you really know in where to look for or how to get the damn job done.

Anyway, just buy one of those scripts and you will be fine.

You can try to look at price comparison in coinmarketcap, but I think in coinmarketcap is less effective because you have to check it manually, if you want to do arbitration I suggest to pick a less popular coin, I've seen price differences between exchangers exceed 100% , but if you choose popular coins usually the price difference is just a little, usually some exchangers will close the deposit and withdraw when the price of the coin has a high price difference with other exchangers.

Helpful, but it does not compare very many different coins.

Maybe this is what you're looking for (livecoinwatch.com), it has lots of altcoin and price is updated in real time. arbitrage is kinda hard to trade, there are bots that are going to be a lot faster than you. also you'll be needing a lot of money for it to be profitable.

Some people to arbitrage trading this way, but to me it seems like the time to transfer coins from one exchange to the other would make it hard to get it timed correctly. Plus there are fees every time you move coins off an exchange. I wonder how much profit you can actually make doing this kind of trading, seem cumbersome.
