Is there anywhere I can find detailed LTC historical trade data? BTC-E's API is not well documented and I can only find a live tick API from them. I found historical data on Cryptocoin Charts but the data they output is not very detailed.
If you search through your BTC-e's profile, you will find that they have MetaTrader which shows all trades.
This site shows data for MTGox which is very good for like how you want though I don't know if they have one for BTC-e
You might want to try http://www.cryptodatasets.com/ It has free raw data and sampled data from Bitfinex and HitBtc (currently), including BTC, ETH and LTC(litecoin). Hope it helps!
P.S. it's my website
