Timer events

[cls71]

Greetings,
Is it possible triggering custom events ?

I'd like triggering one event every second for displaying the current time.
I used System.Timers.Timer but doesn't work. Only displays when receives ticks.


Thanks very much.

publicclass ZiTimer : Indicator
{
#region Variables

private Timer aTimer = new Timer();
privatebool bInit = true;
#endregion

privatevoid OnTimedEvent(object source, ElapsedEventArgs e){
DrawTextFixed("Timer", DateTime.Now.ToLongTimeString(), TextPosition.TopLeft );}




protectedoverridevoid OnBarUpdate(){
if ( bInit ){
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
aTimer.Interval = 1000;
aTimer.Enabled = true;
GC.KeepAlive(aTimer);
bInit = false;}

}

}

This is beyond what we can provide support for. However, here are some hints:
- we usually start timers by timer.Start()
- you should use System.Windows.Form.Timer and not System.Timers.Timer, since the former throws the timer event in the main thread which makes sure you indicator/strategy works as expected
- no need to register the timer at the garbage collector
- NT6.5: please press F1 and scan help guide for TriggerCustomEvent

Thanks Dierk,

but TriggerCustomEvent only works with ticks.
If I want to trigger one event more fast that one tick, doesn't work.

I'm trying with System.Windows.Forms.Timer but it doesn´t work neither.
Only works if receives ticks data.


Thanks very much.




using System.Windows.Forms;

// This namespace holds all indicators and is required. Do not change it.

publicclass ZiTimer : Indicator
{
#region Variables
privatebool bInit = true;
private Timer myTimer = new System.Windows.Forms.Timer();
#endregion



privatevoid TimerEventProcessor(Object myObject, EventArgs myEventArgs) {
TriggerCustomEvent(MyCustomHandler,this);}

privatevoid MyCustomHandler(object state){
DrawTextFixed("Timer", DateTime.Now.ToLongTimeString(), TextPosition.TopLeft );}




protectedoverridevoid OnBarUpdate(){
if ( Historical ) return;

if ( bInit ){
myTimer.Tick += new EventHandler(TimerEventProcessor);
myTimer.Interval = 1000;
myTimer.Enabled = true;
myTimer.Start();
bInit = false;
}


}

We will provide a sample shortly.

Thanks very much, Dierk
I can't wait

Great, will take a little while since the whole team has been in NYC for the show over the last weekend.

Hello Dierk,
excuse me for my wearisome insistence, but could you help me with this problem ?
Thanks very much

[NinjaTrader_Dierk]

Sorry for the delay, this issue is not forgotten. We will post something within the next few days.

I am wrapping up a project that relies on a timer event to take a snapshot of Level 2 values each second. I started with the System.Windows.Form.Timer but since I wanted to capture data from OnMarketDepth() and not the OnBarClose() method, I ended up using the System.Timers.Timer without using a TriggerCustomEvent. The point being it would be useful to see a reference example(s) that can be used across different update methods and not necessarily tied to an incoming tick.

You can use the TriggerCustomEvent across the board. The timer event is just a sample.

Please take a look at this reference sample: http://www.ninjatrader-support.com/v...0463#post30463

Thanks Josh, your reference sample was very relevant and helpful to put the finishing touches on what I was working on.

Thanks very much Josh, but this solution doesn't work if I want to plot one drawstring, e.g.

If NT doesn´t receive ticks, doesn´t plotting.

Is there any way for calling to the Plot method inside one Timer.

Greetings.

[NinjaTrader_Dierk]

Not sure I follow: You can call any NinjaScript method you'd like on the event handler (Draw... methods, order methods, anything). Why would you want to deal with the Plot method?
