There is a difference between signals and trades.  A trade requires a valid entry signal, sufficient equity, and a valid exit signal (or stop).  When you click “all trades”, are you really clicking “show arrows for all raw signals”?  This shows all your signals, not your trades.  There could be many reasons why you do not see as many trades as you expect including:

 

Symbol information not setup (menu Symbol->Information – Contract Specification)

Backtester information not setup (Settings… button in AA – Initial Equity, stops, etc.)

AFL logic does not include exit or stop conditions (i.e. Sell = <Boolean logic>; Cover = <Boolean logic>; ApplyStop();)

AFL logic uses PositionSize which controls equity allocation for each trade

 

Once basic information is setup for your symbols and the backtester, it’s usually your AFL logic that controls the number of trades.

Thanks Brian. I will further investigate this data download issue
during the weekend. I also saw some other posts about the same subject.

Regarding my second question: Who could please explain me this strange
Amibroker concept of backtesting? It's really strange for me to click
on backtest and then only see a few trades in the analysis window and
the backtest report while when I click on show all trades or select
scan I see all the trades.

Thanks.
