Also, you have made/lost money on your shorts which rolls over into the next long trade.

TH--

Because you cannot be long and short the same stock at the same time. Being short may result in you not taking a long position that you entered in a long only test....

Subject: [amibroker] Why  do short trades affect long trades?

Why does the  presence or absence of short trades affect the 
profitability of long  trades?

Example 1: long and  short

...............All......Long.....Short
Initial........10000....10000....10000
Ending.........19947....20531.....9416

Example  2: long  only

...............All......Long.....Short
Initial........10000....10000....10000
Ending.........20914....20914....10000

Reversing  system.  No commissions or  slippage.

Regards,
Alan
