strategy analyzer template with timespan() vars

[enable]

NT8 RC1

Hi,

Saving a strategy analyzer template with string, int, double and timespan vars, works as expected. All data is saved with the exception of the timespan vars. Below is a part of my \NinjaTrader 8\templates\Strategy xml template file (time01, time02, time03 are timespan vars):

<tradetype>Long_Short</tradetype>
<swing_strength>5</swing_strength>
<rrr>2</rrr>
<swing_spread_min>5</swing_spread_min>
<adx_line>20</adx_line>
<trades_day>0</trades_day>
<loss_trades_day>0</loss_trades_day>
<time01 />
<time02 />
<time03 />
<log_file>false</log_file>

Any idea what could cause this problem?

Hello enable,

Thank you for your post.

I am unable to recreate the same behavior on my end. Can you attach the script to your response?
You can find the script under Documents\NinjaTrader 8\bin\Custom\Strategies.

Hi Patrick,

Thanks for your feedback.

aaa_swing02.cs is the stripped down strategy and aa_xml.txt the saved xml template file.

To reproduce the symptom, change any data in the settings (C, D or E), than save it as strategy analyzer template. Open a new strategy analyzer window, click template and load the saved strategy template. Data will get repopulated, only the 3 timespan vars will show 00:00:00 rather than the before saved time.

Hello enable,

Thank you for your response and for sending over the files.

I can reproduce this on my end. I will report this to development.

Hello enable,

Thank you for your patience.

NinjaTrader Serialization to the .xml template is not supported for TimeSpan. You would need to create a serialization on your own.

You could use the following as an example:

[NinjaScriptProperty]
[XmlIgnore]
[Display(Name="MyTimeSpan", GroupName="Settings", Order=0)]
public TimeSpan MyTimeSpan { get; set; }

[Browsable(false)]
public string MyTimeSpanSerializer
{
    get { return MyTimeSpan.ToString(); }
    set { MyTimeSpan = TimeSpan.Parse(value); }
}
