DrawDot...

[Mark-]

Hello,

I am using a tick chart and when a condition becomes true I want to draw a
dot on the current bar at the current price.

I am using:
DrawDot("LogicDot", true, 0, Median[0],Color.Blue);

I am also logging the condition went true and playing a sound. The logging
and sound is working.

The dot is not drawn at the current price or the median price on the active bar.

It appears to draw on the bar the strategy was made active and that can be 10 or more bars earlier.

What am I doing wrong?

Ciao,

DrawDot() draw on the bar it was called. I suggest you print out the timestamp it was called so you can correlate it with the chart.

Print(Time[0].ToString());

Hello

>DrawDot() draw on the bar it was called.

What does that mean?

I know when it is called. I am watching the chart and the sound plays and the output window updates correctly. The dot is not drawn. If I just started the stragety the dot is drawn at the bar the stragery starts.

I will add the timestamp for trouble shooting.

Ok. I just did that and the time is the correct bar.

OK #2 I just verified that the dot is drawn on the bar were the stragety goes active not the time of the current bar.

What am I doing wrong?

Please provide a screenshot. Thank you. Are you absolutely sure that is the code you are using? If you told it to draw at bar 0 it would not draw on a historical bar way in the past.

Hi,

That is what I thought.

I will post a screen shot of the output window and the dot on the tick chart tomorrow.

When normal trading with the DOM, I have noticed the trade entry and exit points on the tick chart are not in the correct locations. But, it did not bother me, so I said nothing.


Till tomorrow,

Please sync your PC clock to ensure accurate timestamping.

Entry/exit plots show up on the first bar with the same timestamp of the execution. If you are using a tick chart that is moving so fast that you have many bars with the same timestamp you may experience what you are describing.

Hello,

The PC clock is sync'd every morning.

> with the same timestamp

I would assume the resoultion is down to the second. So, if three bars appeared in the same second I could see it on the first bar and that makes sense.

What I want to do is draw "anything", that stands out, at the current bar and at the current price under certain logic conditions. I am not using the bar update to draw. I need it to draw at anytime. I am at present using another event to check the logic and I want to draw in that event. Can you suggest a draw command that would let me achive the above?

Thanks,

Mark

Mark,

The Tag must be unique for each bar / time its called, otherwise you will only see the last one.

Use this nomenclature:

DrawDot(CurrentBar.ToString(), true, 0, Median[0],Color.Blue);

hope this helps.

Thanks mrlogik, good point.

Mark, it would be helpful for us to see the code you use to further advise - Thanks!

Hi,

Ok. I have verified that it is only drawing at the bar the stragety is started. I attached the screen shot. The first dot was at :27 and it should have been 28. The second dot should have been at :30:01. But what happened is the first dot disappeared and a new dot appeared on the same bar but at the new price.

The sound plays and the print works at the correct time.
How do I get the current price value?

protectedoverridevoid OnMarketData(MarketDataEventArgs e)

if x
{
PlaySound(@"C:\bbell.wav");
Print("Logic Fired " + Time[0].ToString());
DrawDot(CurrentBar.ToString(), true, 0, Median[0],Color.Blue);
// DrawDot("", true, 0, Median[0],Color.Blue);
}

Thanks,

Mark

Mark.

Like I said earlier, the tag must be unique for each dot draw.

You will get an update for each Tick of the bar, which means for each full bar, you will only plot 1 dot at the very last tick of the bar.

What are you trying to do? Please give some a full description so I can help you more.

Thanks

Hi,

I am sorry, I am confused. I made the change as you suggested.

DrawDot(CurrentBar.ToString(), true, 0, Median[0],Color.Blue);

>What are you trying to do?

I stated what I am trying to do in eariler post.

Mark,

All provided Draw() methods are tied to bars. You can only draw on bars. If you want many draw objects each representing some condition you need to use a more unique string than just CurrentBar.ToString(). That would only get you a unique string per bar which is not necessarily unique enough if you have many draw attempts within one bar. I suggest you use your own counter and each time you add a new object just increment the counter.

Hello,

OK. I can do that but, it seems a point not related to the time and dot not appearing on the correct bar. Did you look at the screen shots I sent? It shows the time logged and the dot are not in sync. What can I do about that problem?

I just have one condition and I want to draw it on the bar. If the dot moves up/or down on the bar that is fine. As long as it is on the correct bar.

This is the problem.
1) I have a condition.
2) I get the time, log it.
3) I play a sound.
4) I draw a dot on the current bar.

1,2 and 3 work without error. 4 fails. What is the solution to that failure?

Ciao,

you MUST have a unique tag for each time you call DrawDot.

Make some global counter,

int x = 0;

each time you call your DrawDot, do this

[FONT=Courier New]DrawDot(CurrentBar.ToString() + x.ToString(), [SIZE=2][COLOR=#0000ff]true[/COLOR][/SIZE][SIZE=2], [/SIZE][SIZE=2][COLOR=#800080]0[/COLOR][/SIZE][SIZE=2], Median[[/SIZE][SIZE=2][COLOR=#800080]0[/COLOR][/SIZE][SIZE=2]],Color.Blue);[/SIZE][/FONT]
x++;

This will give you a unique tag each time. If you DO NOT have a unique tag, you will simple erase the last dot you drew with the same tag.
