Stefano, here is excerpt from the help window
Scan
this starts the signal scan mode - AmiBroker will search through defined
range of stocks and quotations for buy/sell signals defined by your trading
rules.If one of the buy/sell conditions is fulfilled, AmiBroker will display
a line describing when and on which stock the signal has occurred. Next
AmiBroker proceeds to the end of the range so multiple signals on single
stock may be generated.
Explore
this starts an exploration mode when AmiBroker scans through database to
find symbols that match user-defined filter. The user can define output
columns that show any kind of information required. For more information
please check out "Tutorial: How to create your own exploration"
Back Test
this starts the back-testing mode - AmiBroker will search through defined
range of stocks and quotation for BUY signal defined by your buy rule. If
the buy rule is fulfilled, AmiBroker will "buy" currently analyzed shares.
Next it will search for SELL signal. Then, if sell rule is fulfilled,
AmiBroker will "sell" previously bought stocks. At the same time it will
display the information about this trading in the listview. After performing
simulation the summary will be displayed. Read more in "Tutorial: How to
backtest your trading system"...
So in summary
Scan provides the raw buy/sell signals
Explore shows the results of the formulae per the filter and required
columns you add
Back test will provide results of the trades per your formula per the
buy/sell conditions, allowing one trade to be open at any time per stock.
Cheers,
Graham
