Filters combo

August 10th, 2023, 11:15 PM

Hi there,
I’m trying to code a filter combo which will collect useful filter or filters for certain signals from the list. Does anyone know how to finish this?

Code example: (Fx from 0 to 1)
Inputs: Fx1(0), Fx2(0), Fx3(0), Fx4(0); {there could be more Fx}
If Fx1 = 1 then begin
Value1 > Value1[1]; {Trend}
end;
If Fx2 = 1 then begin
Value1 < Value1[1]; {C.Trend}
end;
If Fx3 = 1 then begin
Value3 < AbsValue(Value1 – Value2); {Bios}
end;
If Fx4 = 1 then begin
Value4 < AbsValue(C-Value1); {Bios}
end;
If MP <= 0 and Fx1 and Fx2 and Fx3 and Fx4 then buy next bar at Value11 stop;
If MP >= 0 and Fx1 and Fx2 and Fx3 and Fx4 then buy next bar at Value22 stop;

Thanks for your time.

What are trying to actually do?

This code does nothing other than check to see if Value1>Value1[1] it doesn't actually assign the result to anything

Code

If Fx1 = 1 then begin
Value1 > Value1[1]; {Trend}
end;

If your trying to check whether condition1 is true and then use it later then you need to use a variable to hold the result

Code

Inputs: Fx1(0);
Var: Fx1_Result(FALSE);

If Fx1 = 1 then begin
 Fx1_Result = Value1 > Value1[1];
end;

If (MP <= 0 and Fx1_Result) then buy next bar at XYZ stop;

Note that since Fx1_Result is set to FALSE in the variable declaration it can only be TRUE if both Fx1 = 1 and the condition is met.

Thanks for your reply. Sorry I'm new here and try to build a filter combo or function so I can use it for further develope.

Following your codes I modify mine as below and the editor show me: "Invalid type operation":

Inputs: Trend(200), ShortT(70),
BiosL(60), BiosS(60),
Fx1(1), Fx2(1), Fx3(1), Fx4(1), Fx5(1), Fx6(1);

Vars: Fx1_Result(FALSE), Fx2_Result(FALSE), Fx3_Result(FALSE), Fx4_Result(FALSE),
Fx5_Result(FALSE), Fx6_Result(FALSE), Fx7_Result(FALSE), Fx8_Result(FALSE);

Value55 = XAverage(C, ShortT);
Value66 = XAverage(C, Trend) ;
Value77 = AbsValue(C - Value55);

Condition1 = C cross over Value66;
Condition2 = C cross under Value66;

If Fx1 = 1 then begin
Fx1_Result = Value55 > Value55[1];
end;
If Fx2 = 1 then begin
Fx2_Result = Value55 < Value55[1];
end;
If Fx3 = 1 then begin
Fx3_Result = Value77 < BiosL;
end;
If Fx4 = 1 then begin
Fx4_Result = Value77 < BiosL;
end;
If Fx5 = 1 then begin
Fx5_Result = Value77 < Value77[1];
end;
If Fx6 = 1 then begin
Fx6_Result = Value77 > Value77[1];
end;

If MP <= 0 and Condition1 and Fx1 and Fx2 and Fx3 and Fx4 and Fx5 and Fx6 then buy next bar market;
If MP >= 0 and Condition2 and Fx1 and Fx2 and Fx3 and Fx4 and Fx5 and Fx6 then buy next bar market;

Sorry been busy. May try and test it tonight but just looking at the code.

Code

Condition1 = C cross over Value66;

not sure if you need cross or crosses

Code

Condition1 = C crosses over Value66;

Also just a note. With your 'If' statements, if there's only one statement after it you don't need the loop. So

Code

If Fx1 = 1 then begin
Fx1_Result = Value55 > Value55[1];
end;

can be just

Code

If Fx1 = 1 then Fx1_Result = Value55 > Value55[1];

No problem, sorry for any interruption.

To response:
1) crosses;
2) still got the message "Invalid type operation"

I suspect it's your buy conditions. You used your filter selection inputs which were numbers instead of your RESULT variables which are bools. The invalid type is referring to the condition needing to be a bool.

Forgot to mention that you should set your results to be true if your input condition is zero (assuming you are flipping a zero and one). This will allow your buy conditions to still be met when the filter is off.

Thanks for your respone but I don't really understand, could you please give an example?

Believe he's saying

If MP <= 0 and Condition1 and Fx1 and Fx2 and Fx3 ... and Fx6 then buy next bar market;

Should be

If MP <= 0 and Condition1 and Fx1_Result and Fx2_Result and Fx3_Result ... and Fx6_Result then buy next bar market;

Forgot to mention that you should set your results to be true if your input condition is zero (assuming you are flipping a zero and one). This will allow your buy conditions to still be met when the filter is off.

And here if you want it to be true when input is zero then

Vars: Fx1_Result(FALSE), Fx2_Result(FALSE), Fx3_Result(FALSE), Fx4_Result(FALSE)...

becomes

Vars: Fx1_Result(TRUE), Fx2_Result(TRUE), Fx3_Result(TRUE)....

Thank you both very much, it work and I finish what I want.

Thank you.
