PHP Litecoin ticker for Opensource Exchange

[IamAGentleman]

Okay I am looking to buy a custom-made litecoin ticker for this project: https://bitcointalk.org/index.php?topic=885845, not one that relies on other websites and no copy-pasta. Offering 1 btc

If not on external sites, where would such a ticker actually determine the speculative price of Litecoin compared to some fiat currency or bitcoin? Or do you want the ticker to display the exchange rate from your exchange itself?

If the script uses 3rd part api's to get prices then if those websites are comprimised then the ticker will be and people could purchase coins for cheap. So want a custom-made one and they will have to decide how to generate the prices.

OK, that makes sense then. I'm unfortunately not enough of a PHP-guru, but I can see this happening with some sort of interface and a bunch of implementations.

Then it would be very hard to determine the price.
If I were you, I would take rate from few pages (for example 5 APIs or more) and if any price is different for more than n% (n could be various - about 5%), then don't use that rate in your calculation. Or calculate statistical model (again from a few APIs) and don't use rates that has too high deviation.

Edit: now I see that this is for exchange. So why you then need ticker? Just take rates from your exchange.

I'll be using the ticker to determine the prices for the exchange. It doesn't exist at the moment so I have to use blockchain to debug on all coins LOL.
