monterl_carlo

An experiment in modeling a monte carlo simulation in erlang

API:

monterl_carlo will simulate market prices on a stock exchange.
You can start it and it will execute a function on every tick or you can have it graph a series of prices for you.

###initialize

monterl_carlo:start_link("MSFT",28.61,5,0.1,0.2,1000).

where the parameters are:

1. symbol
2. initial price
3. precision of the price (how many decimals)
4. annual volatility (%)
5. annual expected return (%)
6. update interval (ms)

###Start pumping out data:

monterl_carlo:subscribe("MSFT",fun(X) -> io:format("~p~n",[X]) end).

This will start pumping out the state of the simulation at the interval you specified.

You can stop it by calling:

monterl_carlo:unsubscribe("MSFT").

###Generate graph data

monterl_carlo:graph("MSFT",50, bid).

Where the parameters are:

1. symbol
2. points
3. type of data

currently the types of data are:

• bid
• ask
• both
• statistics
