Hello,
It is perfectly possible but you need to write a loop for that
as shown in the users guide and my other response.

Subject: Conditionnal stops (RE:
[amibroker] trailing stop question from new user)
<FONT face=Arial color=#0000ff
size=2>Hello,
<FONT face=Arial color=#0000ff

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.
<FONT face=Arial color=#0000ff
size=2>
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".

<FONT face=Arial color=#0000ff

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,
