I seem 
to be confusing you, sorry.   I'll try again.
<FONT face=Arial color=#0000ff

For 
longs and shorts, your dollars profit = sell (or short) price minus buy (or 
cover) price.
<FONT face=Arial color=#0000ff 
size=2> 
The 
only difference is "how much did you invest?".   
<FONT face=Arial color=#0000ff 
size=2> 
For 
longs, it's the dollars invested when you buy.
<FONT face=Arial color=#0000ff 
size=2> 
For 
shorts, it's the dollars invested when you short.
<FONT face=Arial color=#0000ff 
size=2> 
In 
both cases, it's the dollars invested on your FIRST 
transaction.
<FONT face=Arial color=#0000ff 
size=2> 
In 
both of your original example, that figure was $1,000.
<FONT face=Arial color=#0000ff

I'll 
give two examples, including commissions:
<FONT face=Arial color=#0000ff

Long 
Trades:
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>    1,500     (sell price * number of 
shares)
<FONT face=Arial color=#0000ff 
size=2>   -1,000     (buy price * number of 
shares)
<FONT face=Arial color=#0000ff 
size=2>        -30     
(buy commission)
<FONT face=Arial color=#0000ff 
size=2>        -30     
(sell commission)
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>       440      (net 
profit in dollars)
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>       44%     (440 / 
1000 * 100) = percent profit
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2> 
Short 
Trades
<FONT face=Arial color=#0000ff 
size=2> 
   <FONT face=Arial 
color=#0000ff size=2>   1,000    (short price * 
number of shares)
<FONT face=Arial color=#0000ff 
size=2>        -500     
(cover price * number of shares)
<FONT face=Arial color=#0000ff 
size=2>         
-30     (short commission)
<FONT face=Arial color=#0000ff 
size=2>         
-30     (cover commission)
  

  
      440     (net profit in 
dollars)
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>       44%     (440 / 
1000 * 100) = percent profit
<FONT face=Arial color=#0000ff

  how is the profit for shorts calculated?  hi 
  chuck, this has confused me a little,i  understand how to work 
  out longs with commisions e.t.c.,but shorts confuse me as i have never 
  used them.  Is it basically the same as  a losing trade when 
  going long.e.g. i buy a stock at $1000 it goes to $500, i have lost 
  %50.(on a long trade), but if this was a short trade i made 
  %50.Peter.--- In amibroker@xxxxxxxxxxxxxxx, "Chuck
