Hello,
The code you refer to was posted by one of AmiBroker
users.
It was in the "comments" section.
1. Did my result match the intended one?
YES, because code produces spike when exit by trailing stop was
generated and
your trailing stops are triggered rarely
2. Could one not get a similar result by displaying the
buy/sell arrows?
Yes, but sell arrows are the same regardless of what was the
reason
of sell (regular signal or stop-generated signal).
And the code referred to visualising only stops.
Instead one would use also PlotShapes function that is better for
that purpose.
3. In the Plot(Sell == 4,....................)
statement, do I interpret it correctly to mean: Plot the value of 4
if the value of Sell equals 4?
Yes, but value 4 is assigned by Equity( 1 ) when trailing stop is
triggered.
So it in fact means plot Spike when trailing stop is
triggered,
4. I am comfortable with the concept that Sell can hold
the values of 0 or 1, indicating False/True. Where does the
value of 4 come from? I could not
find any reference in Help or group messages.
In fact any NON zero value is treated as True and zero is treated
as False.
The value 4 is written back to sell/cover arrays by Equity(1 )
function.

5. If Sell can hold the value 4, can it also hold the values
of 2 or 3 or 5,.........? If so, what are the meaning of the
different values and where can one find the
reference?
Yes it can hold any numerical value,
1 - regular exit
2 - max loss stop
3 - profit target stop
4 - trailing stop
5 - ruin stop (loosing more than 99.9% of equity)
6. I do not understand the need for the Equity statement
above. Can someone explain?
Equity( 1 ) is a special form of Equity() call that
allows to write back signals generated
by ApplyStop to sell/cover
arrays.

Subject: [amibroker] Sell == 4
Hello,
I am relatively new at using the AA part of AB. I've
been able to code a formula to do what I wished and
felt that the ApplyStop function was what I needed. In
reviewing the documentation for ApplyStop, I noted
the following:
For visual conformation of ApplyStop function,
add the following lines below your ApplyStop formula in Indicator
Builder:Equity(1); // THIS EVALUATES STOPSPlot(Sell==4,"ApplyStop
Sell",colorRed,1|styleOwnScale);Plot(Cover==4,"ApplyStop
Cover",colorGreen,1|styleOwnScale);
I included the code in IB and got a result that was a flat
red line with a spike at the sell point then continuing
the flat red line.
My questions are:
1. Did my result match the intended one?
2. Could one not get a similar result by displaying
the buy/sell arrows?
3. In the Plot(Sell == 4,....................)
statement, do I interpret it correctly to mean: Plot the value of
4 if the value of Sell equals 4?
4. I am comfortable with the concept that Sell can
hold the values of 0 or 1, indicating False/True. Where does
the
value of 4 come from? I could not
find any reference in Help or group messages.
5. If Sell can hold the value 4, can it also hold the values
of 2 or 3 or 5,.........? If so, what are the meaning of the
different values and where can one find
the reference?
6. I do not understand the need for the Equity
statement above. Can someone explain?
I have some other questions on the ApplyStop function, but
will hold that for another post.
Regards,
TonySend
