Good project! Unfortunately without accounting of related transaction costs the information is quite useless.

it'll be added soon...stay tuned Smiley

[/quote]I think price of bitcoin in 2018 will be very difficult to reduce to $ 4000- $ 6000 because with the great applications and utilities bitcoin, now bitcoin are increasingly interested countries and save Legal notice. Although some countries are banned bitcoin, I think they are only temporary solutions when they do not know how to control and manage bitcoin transactions.
[/quote]

Why do you think it would be difficult? Do you have any solid, definitive grounds for your suggestion?

Bitcoin already touched 6100 a couple of days ago, there is more to come Smiley

bleutrade uses different symbol for bitcoin cash which is BCC, where other broker use BCH that causes huge number because its compare bitconnect price with bitcoin cash, this is good way to find arbitrage opportunity very quickly


Thanks for the tip Smiley

Another great arbitrage opportunity between XRP/USD

buy on bitsamp, sell on quoine. Both exchanges carry strong reputation and deep volume.




Nice share! Was however going to expect you would have settled for: buying at Bitfinex and selling at Quoine, since it offered a higher percentage return, any reason for that?

Also, I am thinking the addition of an alert system to this tool, would go a long way in making anyone putting the tool to use, increase its efficiency and maximize profit. Hope that won't be too much work, OP?


Buying on bitfinex was also an option, however I had some funds over at bitsamp Smiley


Thats a very good suggestion...What type of alert did you have in mind?
- email alert on select pair, select exchanges (should the price change certain % ).
- a browser alert, perhaps? (Not sure if it would work on windows, I'm a mac guy Smiley
- an SMS alert would be too expensive for my budget for this project right now, sorry...

Thanks. Fees are still work in progress. problem is... fees are often excluded from the public api. How did you go about fetching the data?

When I wrote my first trade lib, my concept was simple to create an order and then call a method that returns the fee for this order. Since most exchanges don't have an API method for this, the exchange interface module usually calculated the amount.

Today, I realized that speed is the key to most arb strategies, so this method is simply too slow. So I usually just use a worst-case guestimation, so the trade will result in profit in any case.


I don't think trade fees are important part of the equation, since 0.50 % is highest i've seen them go. The average is .25.. so we can speculate Smiley

On the other hand.. deposit and withdrawal options and fees can be very decisive factor

I agree with this, it's very little trouble to go and check that out for yourself before you try to do arbitrage with the info presented on your website.
That said, I really think this is very valuable information and I really commend you for listing it on your website for free.

Arbitrage seems to be pretty profitable again with these enormous price swings, depending on wwhat exchanges you choose.


I'm glad you guys finding use for it Smiley

The problem is, that most exchanges have a request limit (only x requests per second, or so). When I started, it was even like 1 request per 15s, or so.

With sometimes hundreds of pairs on an exchange, it takes forever to get all prices. That is why I focus on FIX or at least websocket connections these days.

https://github.com/aviau/cryptocoin-tradelib/blob/master/core/src/de/andreas_rueckert/trade/site/TradeSite.java

These are old sources for REST API's . Haven't updates them in ages, but maybe they help you somehow.


Thanks, I'll take a look. Most exchanges allow up to 60 requests per minute nowdays. I guess I can utilize more ips when the traffic count increases.

bittrex is part of the list.

What kind of traffic can be expected? Where is it coming from? Hows each ad being served to visitors?

My ads for advertising my simple arbitrage app were banned Sad

I prefer CoinMarketCap

it also seems like some exchanges don't update tickers frequently enough Smiley

The greatest issue with arbitrage that I see people fail to mention is the lack of volume/liquidity. The spread on some coins are very large, as much as 10% of their value. It's great in theory that you can arbitrage but with the spread so high it's often not possible in reality. It is with top 100 market cap coins but not the low market cap ones.

Yep, the exchanges blue proposes to arb on have such horrible liquidity that you can make $0.20 and then still the fiat will be stuck on the scammy brokers. But I guess its good enough for him  Grin
Now you're simply trolling. OP never recommended any one exchange and there're a thousand and one of them showing opportunities, so why not stick with the ones you're comfortable with. Again I see no referral or payment links and no virus alert so far, so what's your fact that you're being scammed? IMO, I see method in the tool before us and am digging in to either make money or unveil a fault.

OP, can you effect the filter on exchanges?


thanks for the input. filters will be uploaded sometime toward the end if this week Smiley

It could be nice, I never tried the abritrage but it's interesting. This app could help novices like me in this domain maybe.

You should explain basics, and make it easy to use and it will be much better.  Wink


I'm only getting started, it will get much more user friendly Smiley
459  Economy / Service Announcements / Re: Cryptocurrency Arbitrage App - beta on: February 06, 2018, 05:04:04 AM
Can you also integrate a feature that tells which exchange has it's wallet on maintenance, cos that the leading cause of  arbitrage opportunities these days Smiley


That would be nice, though I don't think this type of info could be fetched.. hehe
460  Economy / Service Announcements / Re: Cryptocurrency Arbitrage App - beta on: February 06, 2018, 04:52:58 AM
Looks nice!

But I would definitely add the trade fees to the calculation. I know it's often tricky, since I had to write such code a couple of times. But it really helps.


Thanks. Fees are still work in progress. problem is... fees are often excluded from the public api. How did you go about fetching the data?
