Haven't worked with the type of situation you describe, but if I make some modest suggestions (probably you've already tried them):[..]
Problem: While my indicator is running, if I modify some value in my text file, these one are not reflected in the print command, Print(TextFile); New value will be display only after I turned off then turn on the indicator.

Normally you don’t have to worry about cleaning up collections yourself: the ELCollections utility will do it for you automatically when a study or strategy is unloaded. However, there may be times when you want to create a temporary collection, do some work with it, and then delete it to save memory. You can do this with the Release function:
Value1 = ListX.Release(ID) or
Value1 = MapXY.Release(ID)
If you release a local collection (created with New), it will be deleted immediately. If you release a shared collection (created with Share), it will be deleted only when it has been released by all studies and strategies that use it.
Hope I said something useful.New value will be display only after I turned off then turn on the indicator.
I did not take care of thatNormally you don’t have to worry about cleaning up collections yourself: the ELCollections utility will do it for you automatically when a study or strategy is unloaded.

Normally this is done implicitly by the program/code itself, so you don't have to make it explicit. However, since your code is in the LastBarOnChart (and thus with real-time data always active) it might be that the ELCollection doesn't make a new connection to your changed file but keep the current one open without reloading it (probably since the connection and the contents of the file are already in the memory). But I'm mostly just assuming since I can't look into the ELCollection file (and am no expert[..]
Is it a good manner to close a collection after each lecture?

). Perhaps TJ or Bowlesj3 can shed some light on it. Code: Select all
VAR:ListID(ListS.New);
value1 = ListS.Readfile(listid,"f:\temp\TestData\DataReady.Txt");
TextFile = Lists.Get(ListID,1);
Value1 = ListS.Release(listid) ;
Code: Select all
VAR: ListID (0);
ListID=(ListS.New);
value1 = ListS.Readfile(listid,"f:\temp\TestData\DataReady.Txt");
TextFile = Lists.Get(ListID,1);
Value1 = ListS.Release(listid) ;Indeed it could be a problem because this is going to be read in a loop. My project is to scan Texts Files for new information. These info will be trade order parameters that will have been sent via Excel. There will be a constant communication between MC and Excel, one speaking to the other via Text files and direct access to Excel cells using XLInputs http://shop.qclsolutions.com/XLInputs-101.htmI don't think this will be a serious memory consumption, since you won't be doing it continuously.
Code: Select all
Inputs: FileName ( "C:\ADE\Data\My_Test.txt" ) ;
Vars: DataMap(ListN.New),
code(0),
x(0);
if CurrentBar > 1 then begin
if ELC.PathExists(FileName) then begin
value1 = ListN.ReadFile(DataMap, FileName);
// Check map count in case file was empty
if ListN.Count(DataMap) > 1 then begin
code = ListN.Get(DataMap,1);
end;
value3 = ListN.Get(code, 1);
X = text_new(d,t,c[1],"");
If lastbaronchart then
Text_setstring(x, numtostr(value3,0));
end
else print ("File does not exist");
end;

Ergebnis (0) ,// Variable for the content || result

Counter = Counter+1 ;// Barcounter one up (for debugg only)
if CurrentBar > 1 then begin // all bars in chart but the current

@TJ and all : I now have code which works fine for me . It now will be easy to extend .
Thank´s to TJ once again .
