Topic: Crypto prices, trades & volume in realtime excluding fake volume (Read 836 times)

Hello!

I've been working on a website for a while now that shows trading volume and prices in realtime excluding wash trading.

My main incentive for creating this site was me getting sick of all the fake volume exchanges listed on CoinMarketCap.
I'm using a list of exchanges created by BTI (http://www.bti.live/exchanges/) and presented to the US SEC when they applied for the BTC ETF.
Some of the approved exchanges still include (+-5%) wash trading on a few pairs and thats why I also wrote an algorithm that mostly detects strange behaviour and filters it out.

The main difference between this site and all other price trackers is that it saves all trades made on the exchange in a Database and then calculates price and volume rather than just trusting the exchanges API.
The site also comes with a REST and WebSocket API for free which you can use to build your own tools (mostly trading bots, I guess).

Feel free to join the Discord (https://discord.gg/eEQq5PF) if you find a bug, have a question or want to submit a feature request!

The website is in active development so expect things to change.

It would be nice if you could exclude fake cryptocurrencies also.
__________________________________________________________________________

Semi-huge update: You can now see liquidity of every asset (collected in realtime from all exchanges' orderbooks), sort tables by clicking their headers and see high volume transactions on selected blockchains (whale alert).
Order book viewing will be enabled soon (for every market).

Update: The RESTful & Socket.io APIs are now fully documented (https://marketcap.cc/api). Both are completely for free and have no limits, because data should be free Smiley If you need a specific RESTful endpoint for your project don't hesitate to contact me, I'll try my best to include it into the API.

Update: You can now see Liqudity of every market, exchange etc. instead of asset-based liqudity only. Ranking for Liquidity also added.

"Update teaser": I am currently working on a full port of the website to an App. The App will be available for Android & iOS, starting with an Android Beta release first. Here is a screenshot of the work in progress:

Great news! Google Play just approved the official App for MarketCap.cc. You can find it here: https://play.google.com/store/apps/details?id=cc.marketcap.app

I will tweak the algo in the future - mainly for Huobi and HitBTC, but thanks for your feedback!

I'm impressed. Your figures highlight just how much fake volume there is on CMC - something I've been telling peeps for years now - well done!

I'm still not sure about some of those exchanges figures though.... but good work nonetheless.

this is great, it's funny how some exchanges report high volume.
But you still have only 15 exchanges in your algorithm which again does not provide accurate information.
Any idea of how to add more exchanges, although small, they still have a certain amount of trading

A familiar look and feel. Congrats on executing your idea. That's what counts.

I think another member suggested that this would absolutely destroy your I/O if you were to take into concern your site blowing up. I can see niche/featured functions like this in something more private.

Always down to help. Good luck!

excluding fake volume

But pundits know that trading volume is an unreliable metric. Almost every cryptocurrency exchange reports larger trading volumes than what they actually have.

On the other hand, order book data is significantly more trustworthy.

It's a good attempt by a smaller company/single person to combat washed trading/market making/market manipulation, whatever new word they are using to call fake trade volumes - It seems like you are making a valid attempt to not counted the millions in faked volume, and even though I'm sure there will be some exchanges that can slip through, I congratulate you on your effort!

I do enjoy the design aspects of your listing site as well. Although I do get the feeling that text is hard to read, especially in dark mode and when you click a coin - the 4 boxes that are all black (black text, black background, etc) is really distracting and I don't enjoy it at all, maybe try it with white text?

Good luck mate, as long as this keeps being updated you'll have a banger on your side!

We can't really make exchanges to stop faking volumes anyway, it will be always happening and I don't think this project is aiming to stop it directly. All I get from OP is to remove those fake volumes from price tracker site and creating a place where people can find a more genuine prices.

Although it might only obvious fake volumem at start and volume fakers won't stop, at least OP has a big efforts to avoid tracking fake volumes and of course the site and algo will improve if OP really commit to develop this.

Not worth talking the site down since it's only been online for roughly a week now.
