I've been working on a free windows portfolio app (http://salerth.github.io/CryptoPath/) and next I wanted to add better charting.  Either just rendering MACD charts, or doing the calculations and showing which markets are in buy/sell phases.

Are there any APIs (prefer not to do screen scraping as it's not as reliable) for getting longer term price histories for different altcoin markets?  The ones I can find seem to be 24hour averages/highs/lows only... am sure I'm missing one!

Thanks

[What It Is]

Hi All,

I'm new to the whole cryptocurrency game, so to help myself make good decisions I wrote the following app...I've found it pretty useful and so I've decided to release it into the wild!  It is most definitely an alpha/beta release.  If you want something rock solid please dont try it, I'm sure there will be bugs and crashes as I've only tried it on 2 different PCs... which is not a very big test case!

What It Is
This application integrates with Cryptsy, BTC-e and MtGox APIs to provide you with

• Overview of your money in fiat currencies
• Automatically display your totals in each exchange (if API keys are entered), plus local wallet totals (entered by you)
  
• Discover best exchange routes between your currencies and a target currency
• Arbitrage - potential profits made trading between a single currency

What It Is Not

• A trade bot - It finds trade routes, it won't execute the trades however... it's up to you to validate it is correct and do what you want with the information
• A local wallet/Multiwallet - You record your coin totals manually in the app.  For security it does not touch local wallets nor require them to be present
• Finished - This is to be considered beta code, I am sure you'll find bugs

Requirements
Windows
.NET 4.0

Sorry! as much as I prefer the linux/mac world, I find .NET the easiest/quickest to make thick client GUIs.

Security

• Nobody knows me - This is released free and open source.  I saw a few other apps on here that were paid for but the closed source made people worried so I'll stick to donations and open source
• Nobody knows me, and this is an EXE - Until people vouch for the safety, please take any precautions necessary.  The source code is available on the same site, and make sure to virus scan.  Also until you are happy it's not a virus, you do not need to enter your API keys.  Use a VM, whatever you need.  I obviously promise it is not malware, but again I'm new so that means nothing  
• Source - Source code is in .NET 4.0, using Visual Studio 2013.  The express version of Visual Studio 2013 is free
• Exchange API keys are optional - If you do not enter your API keys, the app won't know your exchange totals.  For find profitable exchanges this isnt the end of the world, it just means they are slightly incorrect as they incorrectly factor in deposit/withdraws

Anyway, a few screenshots! More info, a quick getting started guide and latest download link on the github site : http://salerth.github.io/CryptoPath/

If you do decide to try it and find issues (or have suggestions), please PM me or post here.  If you send screenshots or the log file (messages.log) please make sure there is nothing sensitive in it first.
