When I put any of functions starting with "Simulation...", System Tester shows all simulation results as 0s. Why?

Thanks..

This is a result of the normally working simple system simulation. When I put any of the "Simulation..." functions (Simulation.CurrentPositionAge or Simulation.CurrentPositionValue) in any of the order codes, the result becomes all 0s, no position is taken:

First of all, thank you.

Actually, I have found codes on the forum by searching and put them as they are. System Tester did not work. For instance, as simple as this code: Simulation.CurrentPositionAge >= 3. When I put this into Buy to Cover Order, the simulation which is normally working became not working. If you can give me a piece of code to try, I can try and reply back with the results.

Lastly, what about this?
If(Simulation.CurrentPositionValue IS NOT NULL ?,Simulation.CurrentPositionValue=Simulation.CurrentPositionValue,Simulation.CurrentPositionValue=0);
IF(Close>=Simulation.CurrentPositionValue, ATR StopLoss Condition Comes Here, Normal Position (Buy or Sell) Condition Comes Here)

Justin, thank you again.

I have also found ValueWhen(1,Simulation.CurrentPositionAge=0,OPEN) on the forum and tried the following as an Sell Order:
ValueWhen(1,Simulation.CurrentPositionAge=0,OPEN)<=ValueWhen(1,Simulation.CurrentPositionAge=0,OPEN)-ATR(20)
It did not work at all.

Justin,

Thank you.

However, in "2 state" condition for instance, bc only returns "1" at the intersection point. However at that point other conditions have not been met yet. I want MetaStock to signal when all conditions first time met. For instance;

bc:=Cross(C,Mov(C,20,S)){buy signal condition};
sc:=Cross(Mov(C,20,S),C){sell signal condition};
trade:=If( bc=1, 1, If(sc=1, 0, PREV));
cross( trade= x, 0.5)
when(a>=b)

Now it is 05.08.2009 bar number 10: Close crosses over Mov(C,20,S) which means bc=1 however a is still below b so there is no signal produced.

Now it is 05.08.2009 bar number 11: Close is no longer crossing Mov(C,20,S) (Close is now above it) which means bc=0 and a is now above b (a>=b is true) so there is no signal produced.

Now it is 05.08.2009 bar number 12: Close is no longer crossing Mov(C,20,S) (Close is now above it) which means bc=0 and a is still above b (a>=b is true) so there is no signal produced.

Now it is 05.08.2009 bar number 13: Close is no longer crossing Mov(C,20,S) (Close is now above it) which means bc=0 and a is still above b (a>=b is true) so there is no signal produced.


If I convert the code into the following:
bc:=C>=Mov(C,20,S){buy signal condition};
sc:=Mov(C,20,S)>=C{sell signal condition};
trade:=If( bc=1, 1, If(sc=1, 0, PREV));
cross( trade= x, 0.5)
when(a>=b)

Now it is 05.08.2009 bar number 10: Close crosses over Mov(C,20,S) which means bc=1 however a is still below b so there is no signal produced.

Now it is 05.08.2009 bar number 11: Close is no longer crossing Mov(C,20,S) (Close is now above it) which means bc=1 and a is now above b (a>=b is true) so there is signal produced.

Now it is 05.08.2009 bar number 12: Close is no longer crossing Mov(C,20,S) (Close is now above it) which means bc=1 and a is still above b (a>=b is true) so there is signal produced.

Now it is 05.08.2009 bar number 13: Close is no longer crossing Mov(C,20,S) (Close is now above it) which means bc=1 and a is still above b (a>=b is true) so there is signal produced.

I want only the signal at the 11th bar to be produced and no more, it is time all the conditions are FIRST met. Isn't is possible?

P.S.:
1. Why 0.5 in the following?: cross( trade= x, 0.5)
2. I have read the PREV function in the manual, however, what is the following one referring to?: trade:=If( bc=1, 1, If(sc=1, 0, PREV));
3. Is there any sources about this programming language other than the official manual?

Thank you so much. I appreciate your help very much.
