This is a little tool for helping with capital gain calculation for crypto currencies. It uses ledger-cli.org style account books and spits out a csv file like the following:

Short term Trades
Shares	Symbol	Buy Date	Sell Date	Sell Price	Buy Price	Gain	Running Total Gain	Refs
XXX	FOO	2015-10-22	2015-10-22	XXX	XXX	XXX	XXX	S: bittrex.dat:43 foo.dat:44 B: foo_adj.dat:7

The "Refs" column pointa to the file number, line number(s) of the individual ledger posting used, so it's easy to track what this program does. Each line shows the "S", sale, and "B", buy of the coin, and intra-day entries are combined. For example, on line 1, bittrex.dat:43 means the bittrex.dat ledger file, line 43, and an example ledger entry might be:

2015-10-22 12:45:01 * Trade
   Assets:bittrex           XXX BTC
   Assets:bittrex           -XXX FOO
