Mop: track stocks the hacker way

Mop is a command-line utility that displays continuous up-to-date information about the U.S. markets and individual stocks. One screenshot is worth a thousand words:

Installing Mop

Mop is implemented in Go and compiles down to a single executable file.

$ go get github.com/mop-tracker/mop/cmd/mop

Alternatively,

# Make sure your $GOPATH is set.

$ git clone https://github.com/mop-tracker/mop
$ cd mop
$ go build ./cmd/mop
$ ./mop

Using Mop

For demonstration purposes Mop comes preconfigured with a number of stock tickers. You can easily change the default list by using the following keyboard commands:

+       Add stocks to the list.
-       Remove stocks from the list.
o       Change column sort order.
g       Group stocks by advancing/declining issues.
f       Set a filtering expression.
F       Unset a filtering expression.
?       Display help screen.
esc     Quit mop.

When prompted please enter comma-delimited list of stock tickers. The list and other settings are stored in the profile file (default: .moprc in your $HOME directory)

Expression-based Filtering

Mop has an in realtime expression-based filtering engine that is very easy to use.

At the main screen, press f and a prompt will appear. Write an expression that uses the stock properties.

Example:

last <= 5

This expression will make Mop show only the stocks whose last values are less than $5.

The available properties are: last, change, changePercent, open, low, high, low52, high52, volume, avgVolume, pe, peX, dividend, yield, mktCap, mktCapX and advancing.

The expression must return a boolean value, otherwise it will fail.

For detailed information about the syntax, please refer to Knetic/govaluate#what-operators-and-types-does-this-support.

To clear the filter, press Shift+F.

You can specify the profile you want to use by passing -profile <filename> to the command-line.
