[amibroker] What's wrong with this backtest?

Thanks 
for the feedback. All my settings were straight from help scenario#1. My 
delays were set to 1, setting delay to zero, gives even higher profits with 
Activate StopsImmediately set to TRUE or to FALSE. I tried 1-Minute data as 
well as EOD data, both give me HG profits.

So, 
how do i use this stop? It must be there for a purpose. I am looking 
for a working example for this type of stop... the idea appears good.

  Note on using 
  stops:Scenario 1: you trade on next bar OPEN and 
  want to exit intraday on stop priceCorrect settings: 
  ActivateStopsImmediately turned ONExitAtStop = 1Trade delays set 
  to oneTrade price set to openScenario 2: you 
  trade on today's close and want to exit intraday on stop priceCorrect 
  settings: ActivateStopsImmediately turned OFFExitAtStop = 1Trade 
  delays set to zeroTrade price set to closeScenario 
  3: you trade on next day OPEN and want to exit by stop on OPEN 
  price when PREVIOUS day H-L range hits stopCorrect settings: 
  ExitAtStop = 2 (NEW)Trade delays 
  set to oneTrade price set to open
  
  
    a) (if you want to have stops executed AFTER regular 
    signals, so cash from stopped out positions is NOT available to enter trades 
    the same day) ActivateStopsImmediately turned ON 
    b) (if you want to have stops executed BEFORE regular 
    signals, so cash from stopped out positions IS available to enter new trades 
    the same day)ActivateStopsImmediately turned OFF 
  
  Scenario 4: you trade on 
  today's close and want to exit only when today's close price hits the stop 
  levelCorrect settings: ActivateStopsImmediately turned 
  OFFExitAtStop = 0Trade delays set to zeroTrade price set to 
  close

    You're right, Dingo. If you comment out the activate stops line, the 
    obscene profits die. In real trading, you would indeed activate your stops 
    immediately, but in backtesting, you cannot, using EOD data, since AB can't 
    know when the stop was hit relative to the entry time. Thanks for 
    pointing the stops line out.

        Question
        
        <FONT face=Arial color=#0000ff 
        size=2>Using the profit trailing stop we enter on the trading system but 
        exit on the stop. Since the system (i picked it for illustration only) 
        gives only occassional signals exposure is thus very low: we are 
        never more than one bar in the trade. That part looks alright 
        to me. However the profits are unreal. telling me there is something 
        wrong but i can't figure out what. I am using AB
