how to initiate a trade from a chart object

[td_910]

Hi,

I'm trying to code a strategy/indicator, that is initiating trades based on chart objects, that get drawn by hand or any other indicator.

How I gonna do that?

(it's seems to be possible, there is something out there, that claims to do right that)

Hello td_910,

Thank you for your note.

This would be possible by looping through drawing objects applied to a chart and if a specified drawing object is present you could take some action, ie EnterShort();

I have attached 2 indicators both starting with the name Loop, which demonstrate how you can loop through drawing objects and identify a specific type, ie ArrowLine.

A link to our helpguide covering order methods can be found at the following link,

Hi Alan,

Thanks for that. Is that also possible in NT7?
I always thought, that an indicator/strategy is only able to access it's "own" drawing objects?

Hello td_910,

The loop I provided would pick up on manually drawn objects not just those drawn by the indicator.

This should be possible in NT7 using the loop at the following link,

Please let us know if you need further assistance.

yes, right it does pick up all draw objects, but only the ones drawn by the indi the loop is in and the manually drawn ones

what it doesn't pick up is all other drawing objects drawn by other indis on the same chart

I used that in my code
if (FirstTickOfBar) foreach (IDrawObject draw in DrawObjects)
{
if (draw.DrawType == DrawType.Text) Print(draw.Tag);
}

Hello td_910,

This was an improvement in NT8, where the draw loop could pick up on objects drawn by other indicators. This is not the case in NT7.

Please let us know if you need further assistance.

that sounds great, I just have a couple 100k line of code in NT7
is there some "converter" to migrate that to NT8 ;-)

Hello td_910,

There is not an official indicator/strategy converter which takes scripts from NT7 and converts them to NT8 however on the forum there is a post which provides script for conversion.

I’d like to mention its best to do a manual conversion for accuracy as not all scripts are simple enough to be converted directly.

Also below I’ve provided a link to code breaking changes which you should consider when converting your scripts:

Converting customer code is out of the scope of NinjaScript support however if you’d like I could have someone from our business development team pass over a list of third party developers that you could contact about debugging your code.

Please let us know if you need further assistance.
