Conditionnal stops (RE: [amibroker] trailing stop question from new user)

I 
don't think it is possible right now. The only way I can imagine would be 
through the Equity(1) function, but even that doesn't work properly. In fact, 
the Equity(1) function writes down the stops to the "sell/cover" 
variables, but doing so, new buy/short signals can be generated after the first 
stop that can modify the following positions. You should iterate the whole 
formula the same number of times as there are stop signals. I think it 
would be possible through a "WHILE" loop, but it doesn't seem a very sound 
process.

A 
better solution would be to have a "condition" parameter in the "ApplyStop" 
function, related to the state (in terms of profit and number of bars since 
opening) of the current opened position. Something like 
: 
 
<FONT face=Arial color=#0000ff 
size=2>"ApplyStop(type,mode,amount,condition,ExitAtStop,Volatile)"
<FONT face=Arial color=#0000ff 
size=2> 
A 
concrete example :
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>"ApplyStop(StopTypeLoss, StopModePoint,5,"Profit > 10 and Nbars 
> 5",true,true);"
<FONT face=Arial color=#0000ff 
size=2> 
<FONT face=Arial color=#0000ff 
size=2>"Profit" and "Nbars" could be something like "internal variables" and you 
could imagine to be able to decide if "Profit" is using a percent or mode 
value.

With 
theses conditionnal stops, you can imagine any combination of stops according to 
the way your position is evolving. For example : "after 10 days, exit the 
position if it shows a loss, otherwise, use a trailing 
stop".

Would 
you find this feature interresting ? Tomasz, would it be a nightmare to 
code ?

  [amibroker] trailing stop question from new 
  userHi,I am trying to implement a two 
  tiered stop loss, one part being a trailing stop, the other a fixed stop. 
  I want a 3% trailing stop if I am at least 10% profitable, else I want a 
  fixed stop loss price.I thought I had it, but can't quite figure out 
  how to utilize a variable in the ApplyStop(2,x,3,true,false) command. It 
  is the "x" I just showed that needs to be a 1 to enable, or a 0 to 
  disable.Here is a portion of my 
  code:==================================================...BuyPrice 
  = Max(BuySTOP,Low);SellPrice = 
  Min(SellSTOP,High);profit_ten_percent = (((High - BuyPrice)/BuyPrice) 
  >= 0.10);enable_stop = 
  IIf(profit_ten_percent,1,0);ApplyStop(2,enable_stop,3,True,False);Sell 
  = 
  Cross(SellPrice,Low);==================================================It's 
  the "enable_stop" variable that fouls this up. Is this strategy even 
  possible? I would greatly appreciate any help on this.Thank you,
