Drawdots under each bar?

[mefTrader]

Hi,
Coming from TS and used to TS Showme functions that puts dots under/over a bar depending on a variables and show historic variables settings too.

Let me explain

1. The following code puts a single dot under say an entry point loong/short

TrStop.Set(Low[0] - StDev*1.382);
DrawDot("TStop_Long", true, 0, TrStop[0], Color.Blue);

2. Moving the stop along the bars I am then changing the variable
if (TrStop[0] == 0) TrStop.Set(Close[0]);
if (Close[0] > Close[1]) TrStop.Set(Low[0] - StDev * 1.382);
if (Low[0] - High[1] > StDev) TrStop.Set(Low[0] - StDev * 0.618);
if (TrStop[0] < TrStop[1]) TrStop.Set(TrStop[1]);
DrawDot("", true, 0, TrStop[0], Color.Blue);

But the dot does not stay under that completed bar - seems it is deleted and put on the next bar ( the last bars seems to have a dot!)

How can I put a dot under each bar as the trade progresses?

mefTrader, when drawing objects there is a need to specify a tag inside quotes. When the tag is the same for every draw object, that same object will be drawn over and over again. To create more than one object, they need different identifiers. CurrentBar is the number of the bar the indicator is currently "thinking" about and is useful for this purpose:

DrawDot("dot tag" + CurrentBar, true, 0, TrStop[0], Color.Blue);

great thanks

I found the use of DrawDot("dot tag" + CurrentBar... to kill the performance of NT 7. Memory consumption and CPU spike and NT locks up for minutes. Running on brand new 6 core processor computer. Is there another way to draw dots ( and other graphics objects ) on every bar?

[NinjaTrader_Bertrand]

Brillo, unfortunately not - do you see this on backtesting or on the regular charts when the indicator / strategy is running? How many objects are you drawing approximately as you see this happening?

Thanks

It's backtesting a 24/7 ES 20 tick 3 days. I've stopped using the drawing objects on every bar as it's really usable. It would appear that the architecture is creating a separate GDI object for each and every bar. This is wasteful.

[NinjaTrader_Bertrand]

Thanks for clarifying - you would indeed create an object for each dot then, in back testing in the Strategy Analyzer we would suggest to not draw them at all in your strategy.

Brillo, is there any reason to not use a dot Plot under every bar instead of a Draw object?

Probably not! I don't know about DrawObject. I was going by the suggestion I found here in this thread. Can I use DrawObject to draw the dots and use less system resources?

Unfortunately, I'm not sure what you mean. At first I thought you were saying that there's an alternative way to draw dots called a Draw object that is better then the DrawDot api that I'm using. But on a second read of your note it's not clear.
