This is a total newbie question:


Can anyone  point me to an example of backtesting a signal? That is, say I have a csv with lines like:

2016/01/15 9.37am, AAPL, Strong Buy
2016/01/15/9.49am,MSFT, Weak Buy

.and in the backtest I want to act on the signal when it occurs. I see in the docs how to connect an external data source, but would just like an example of a backtest using an external signal like that.
