Robert,
This will take some coding on your part since only you know what you
want to do with arbitrating the various rules.
You would replace your AlertIF statement in each of your 9 charts with
code like this:
If (Buy) StaticVarSetText("exec_1","script/file to
execute goes here");
In your 2nd chart it would look like this:
If (Buy) StaticVarSetText("exec_2","script/file to
execute goes here");
Then you will have a TimerControl.afl that reads each of these. See
below for code sample. I have extracted this code from my own, working,
TimerControl module that sends out email alerts to me at designated times for
multiple charts so it's not quite the same, but adaptable.
You could put your Chart 3 "time" code into TimerControl and
eliminate Chart 3 from your screen. Maybe someone else has a better time delay
function than mine.
Note: If you’re reading data very fast, this may not work as expected
or it may miss some signals. You’ll have to try it out to see.
/*************** Timer Control Code ******************/
function wait (Seconds)
{
end = Now(4) + Seconds;
while (Now(4) <= end)
{
sin(sqrt(123456789)); //Just to
kill some time
}
}
/* Loop through up to 10 charts executing scripts for
those with data available. This has a roughly 1 second delay between executing
each chart that has a signal. This may be inappropriate for you. You may also
need to collect all 9 charts and make decisions on which to execute */
varName = "";
for (i = 1; i <= 10; i++)
{
varName = "exec_"
+ NumToStr(i,1.0);
//Build the name of the current
chart being read.
varMsg =
StaticVarGetText(varName);
if (varMsg == "")
varName = "";
else
{
AlertIf(True,"EXEC",
varMsg, 6,1+2,0); //Check options
StaticVarSetText(varName,””);
//blank for next tick
wait(1);
//1 second delay before reading next chart
}
}
//Chart 3 code. Delete Chart 3 and replace with this module
AddColumn(Hour(),"Hour");
AddColumn(Minute(),"Minute");
function time()
{Time = Now(4);
Seconds = int(Time%100);
Minutes = int(Time/100%100);
Hours = int(Time/10000%100);
SecondNum = int(Hours*60*60+Minutes*60+Seconds);
return Time;}
Title ="\nTime: "+NumToStr(Time(),1.0,0);
/*************** End Timer Control ******************/

| Dear Terry,
|
| thank you very much for your help.
|
| I am not too deep into AFL coding.
|
| Could you help me out with a concrete sample for the code ?
| Below as an example.
|
| Thank you !!!!
|
| Regards
| Robert
|
|
| Examle for my current setup:
|
| Chart 1 (EURUSD)
|
| Buy = Cross(condition);
| Sell = 0;
| Applystop...(loss limit)
| Applystop...(profit Target)
| alertif(Buy,"EXEC" .....,1);
|
| Chart 2 (USDJPY)
|
| Buy = Cross(condition);
| Sell = 0;
| Applystop...(loss limit)
| Applystop...(profit Target)
| alertif(Buy,"EXEC" .....,1);
|
| Chart 3 (time)
|
| AddColumn(Hour(),"Hour");
| AddColumn(Minute(),"Minute");
| function time()
| {Time = Now(4);
| Seconds = int(Time%100);
| Minutes = int(Time/100%100);
| Hours = int(Time/10000%100);
| SecondNum = int(Hours*60*60+Minutes*60+Seconds);
| return Time;}
| Title ="\nTime: "+NumToStr(Time(),1.0,0);
