SampleCustomEvents

[ATI user]

if you put a print statement in either OnMarketDepth(MarketDepthEventArgs e) it prints on every orderbook update

if you put a print statement in MyCustomHandler(object state) it prints every 1000ms

however if you put a DrawText statement in with the print statements you do not get the same updates in the chart...i.e. the interval of the prints to the output window and plots on the chart do not match....chart is much slower and misses many of the updates...i.e. lags what is actually going on

same lag if you plot a line using myline.Set(value);

Why is the chart not plotting at same interval?

In addition to the "Display Update interval" property on your chart, the Draw() methods are not called the same as Print()

You'll notice if repeatedly click on the chart, you should be able to get the Draw method to update almost as quickly as your output prints.

This can be worked around by over ridding the plot method however. You can look at the BarTimer indicator to get an idea of how you accomplish this.

changing "Display Update interval" property from 0.5 to 0.1 had no effect so changed it back to 0.5

copied some of the code from the BarTimer indicator into my indicator and now it plots every 1000ms per the default timer setting in my indicator

works great...thanks

To clarify, Display update interval only affects the OnBarUpdate events.

excellent..thanks

spoke too soon....

"Error creating window handle."

Edit Ninjascript could not pull up dialog to select indicator to edit.

could not exit ninja... closed with TaskManager

had copied from OnBarUpdate:
if (DisplayTime()){
timer = new System.Windows.Forms.Timer();
timer.Interval = 100;
timer.Tick += new EventHandler(OnTimerTick);
timer.Enabled = true;}

on restart copied from onbarupdate:
if (timer == null){
if (DisplayTime()){
timer = new System.Windows.Forms.Timer();
timer.Interval = 100;
timer.Tick += new EventHandler(OnTimerTick);
timer.Enabled = true;} }

had copied from bartimer indicator Misc region:
DisplayTime()
DateTime Now
OnTimerTick(object sender, EventArgs e)

on restart copied from bartimer indicator Misc region:
OnTermination()

have not copied:
Plot(Graphics graphics, Rectangle bounds, double min, double max)
since I do not want bartimer plots

working fine now...waiting to see if lock up recurs
