  Position Size Shrinking
  
  Terry,
  Do 
  you mean MORE than your original equity? If my first trade was a loser, say I 
  lose 25% of a $40k initial equity. Wouldn't AB just size the next trade for 
  the remaining $30k? I am still confused about this.
   
  I 
  have "Min. shares" set to 100 because I don't want to trade anything less than 
  that.
  I 
  have "Round lot size" to 100 because I like round lot sizes of 
  100.
  I 
  have "Limit trade size as % of entry bar volume" set to 
1%.
  I do 
  not have "Use previous bar equity for position size" 
  checked.
   
  Is 
  there some kind of matrix somewhere which shows the relationship of the 
  different AA settings?
   
  Thanks for your time, Scott
  
    Position Size Shrinking 
    let's you take a trade with LESS than your
original equity. If it's not 
    checked and your first trade is a loser,
you don't get any more trades. 
    There are other things that affect your
trading too such as minimum 
    shares, round lot size, use previous bar for
equity and limit trades size 
    as % of equity. These are all in
AA->Settings.

    Shrinking
| 
| 
| In the AA Backtester Settings there is a option 
    to "Allow 
| position size shrinking". This option makes a huge 
    difference 
| in my results. I need to understand what AB is doing when 
    it 
| is checked so I can replicate it in my real trading. Below is 
| 
    the help description:
| 
| "If you mark this box AmiBroker will shrink 
    down positions if 
| available equity is less than requested position 
    size (via 
| PositionSize variable). If this box is unmarked positions 
    
| will not be entered in such case."
| 
| This help statement is 
    not really clear to me. Does AB 
| determine "requested position size" 
    independent of available 
| equity? I am not using any "PositionSize" 
    variables in my 
| formula. Is there another "setting" that controls 
    "PositionSize"?
| 
| Could someone explain how I relate this to 
    trading my signals?
| 
| Thanks, Scott
