One click chart trading

[VolatyTrading]

Is there a function I can call within OnRender() to draw a price marker at a specific price?

We have developed an indicator called Clicker for one-click order entry on charts. In short, it shows an order preview at the mouse pointer when the modifier keys are pressed (e.g., CTRL for buy and CTRL+ALT for sell). When the mouse button is clicked, an order is sent.

The issue is that we have to use a plot series to draw the price marker and sometimes it gets out of sync with the order preview. Even when we call it using TriggerCustomEvent()right before drawing the order preview. Is there a direct way to render a price marker without having to use a plot series? I have seen a few requests for this feature in the past. Are there any updates on this?

Hello VolatyTrading,

Thank you for the post.

There is currently no supported api for drawing in the price axis and using a plot would be the suggestion for what you are trying to do.

I can't really tell from the video where it is getting out of sync however if it relates to rendering and the chart just not being updated at that time you may be able to force a render. you can add then immediately remove a drawing object as a means to re render the chart. Removing a drawing object should cause a re render, in your method you could draw a dummy object and then remove it as the next line to trigger that. That would be my only suggestion in case the chart is not updated with the mouse movement in some way.

I look forward to being of further assistance.

NinjaTrader_Jesse thanks, the issue does not show up in the video, but does happen every once in a while. Where can I add/remove the drawing object? I assume it should be done outside of OnRender() in order to trigger a rerender so, say, calling Draw.Arc()and then removing it whenever the mouse moves should work?

Hello VolatyTrading,

You would need to be the judge of where to add that based on where the problem is happening. I couldn't really make a good estimate from the provided information other than potentially the mouse event as you noted. You would have to give it a try and see if there are any performance impacts or if the problem is resolved at all by doing that.

You could do something as simple as:

Draw.Dot(this, "tag1", false, 0, 0, Brushes.Transparent);
RemoveDrawObject("tag1");

I look forward to being of further assistance.
