Or you can put it in a function by itself.
I put it in OnTick() function but you might want to run it in the timer function eventually because now it has to receive a tick in order to change state and if you place the order before a new tick arrives it will still have the old state which can be undesirable but then again the timer does not work in the tester so this is better for testing purposes but eventually switching states in the timer function will be a lot faster and will also work when market's closed and there are no incoming ticks just remember that because you don't want to end up asking yourself why it isn't working to discover it's only because there are no incoming ticks.

Man, I do not try yet, I feel your 2 comments will finished my that part of my EA's code.
Huge thanks, you correctly understand me.
One more thanks a lot man, I solve my issue with your great help.
Can I use OnChartEvent() instead of OnTick(), is it possible?
I already tried, I do not see any problem yet, but you used OnTick() function, just I want to be sure about.
@Marco just I want to ask is there any wrong about image places, because when Off ( / False / 1 ) Stop Loss active, and when On ( / True / 0 ) Stop Loss inactive. ( Just I would not like to change anything, this bitmap very dangerous for me, no kidding - I see it still takes long time from me )
Also I need to ask before I start to try, is there any specific things to use about Global Variables for Bitmap Label Object? ( my ask reason I just see Bitmap Label Object needs something quite different then others... and so on )
Thanks in advance.
No you can just follow the documentation.
And yes it is possible to use it in the OnChartEvent() but remember that you can not include for example trailingstop code because it will only run one time when you click it.
For the bitmap issue go to the folder and rename on to onOLD, then rename off to on, and then rename onOLD to off this should solve your problem by just renaming both files.
Or you can use these buttons below.
I can also resize them if you need something smaller.
Renamed worked for me, but I feel I will check it once again, because in your code it works correctly.
Global Variables: I tried like below code for it but no results even I see it in the Global Variable Window.
use_stoploss_gv = _Symbol + "test BmpLabel GV";
if ( GlobalVariableCheck( use_stoploss_gv ) == true )
{
use_stoploss = GlobalVariableGet( use_stoploss_gv );
}
else
{
GlobalVariableSet( use_stoploss_gv, use_stoploss );
}
You made a lot for me, big thanks man.
//| Expert initialization function |
//+------------------------------------------------------------------+
int OnInit()
{
//---Global Variables
string use_stoploss_gv=_Symbol+"test BmpLabel GV";
if(GlobalVariableCheck(use_stoploss_gv)==true)
{
use_stoploss=GlobalVariableGet(use_stoploss_gv);
Print(use_stoploss_gv," Exists");
}
else
{
GlobalVariableSet(use_stoploss_gv,use_stoploss);
Print(use_stoploss_gv," Created");
}
return(INIT_SUCCEEDED);
}

Seems to be working.
Marco vd Heijden:
Seems to be working.
But it does not save last changes.
e.g: I add it to chart, then I switch it to turn 'On' and then switch to another timeframes, it return 'Off', it is not normal.
And I am using Global Variables for another functions 'Lot, Stop Loss, Take Profit' that works perfectly, but this Bitmap Label does not work.
Please, help me or give advice for how can I solve this Bitmap Label issue.
Thanks a lot man.
Below code works perfectly after you helped me, thanks man.
And I renamed as you said, it works good, but just I am wondering, am I doing something wrong?
( just I am Worry about )
void ordersell()
{
CheckStopLossState();
if ( use_stoploss == 0 )
{ sl = Bid + points_to_change( stoploss * 10 ); }
if ( use_stoploss == 1 )
{ sl = 0; }
OrderSend( ... sl, ... );
return;
}
Thanks in advance.
