How (and where) to trade a person with 400 BTC ?

[sbrzol]

- the person has no any trading experience  (and never learned trading)
- the person can write any application using exchanges API  (.Net, C#)
- the person does not want to use any other (not open source) trading application

Where can find the person good trading source about btc trading?


first (and perhaps only) thought to implement :
if the last price is XX then put a buy order at XX-20$  and a sell order at XX+20$ (refresh it every 10sec)  it there is flash crash (like last time to $275 and back to $310) or a flash jump (to make profit)

others? so simple methods?

or arbitraging ?
i saw arbitrage opportunity yesterday , for example okcoin was about $7 higher than bitstamp  ,
so if i sell at okcoin and buy (back) at bitstamp at the same time and wait until the the price equals then buy btc at okcoin and sell BTC on bitstamp (at about same price, same amout ) and if Okcoin is again at about $7 higher than bitstamp repeat the previous method

Nothing new in that topics ,   "as OP says no cash withdrawals are considered" , so me,  but a lot of commenters did not "understand" that
(lakebtc has high btc withdrawal fees, i will check bitstamp and others )
