    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
