ToTime() not working

[mntemel]

Hi,

I tried adding a time constraint in my strategy but can't get it working. I want to add a "maximum 15 minute" rule between two swing highs that I capture in previous steps. I used ToTime() function as it was described in the Help Menu.

if (model_A && ToTime(Time[new_swing_high])-ToTime(Time[old_swing_high])<=1500)
	{
	 Order Rules ...
	}

My script compiles and strategy executes orders as if there's not time constraint. Any idea where i'm going wrong?

Thanks
MT

Use Print to print out your computations to the Output window.

You will eventually find the issue. It could be model_A or your swing time calculations.
Impossible to tell from here.

Hello mntemel,

Thank you for your note.

Sledge offers a great suggestion, I too would suggest adding print statements to check the value of your variables. I’ve provided a link to a youtube video which covers an example of using prints to understand behavior:

ToTime not working...

if ((ToTime(Time[0]) < 91000)
&& Time[0].DayOfWeek != DayOfWeek.Sunday)

{
Print("true");
}

I ran this at 092000 and outputted "true".... ideas why?

Output window gives 20180702,85900 which is the date and time stamp for the end of the primary series.



Regards and thx

Hello everington_f,

Thank you for your note.

If you use the following if statement do you get the results you desire?

if ((ToTime(Time[0]) <[B] ToTime(8,10,00)[/B]) 
&& Time[0].DayOfWeek != DayOfWeek.Sunday)

I look forward to your reply.

No same problem.

Should I add a new tick series and reference that to get the current time? All I want is easy access to the computer clock current time.

Hello everington_f,

What period data series are you running this on?

If you run this on a 1 minute chart do you see different results?

I look forward to your reply.

Gold overnight session 1108 minute ... so ToTime simply prints the end timestamp of the bar series. Added a tick series but it crashed NT twice.

Simply want to trade once per session... but cant rely on ToTime to reset the counter.

Hello everington_f,

I would suggest adding a 1 minute data series, since the period you are applying the strategy to is 1108 minutes, and a 1 minute series will have a close every 1 minute.

Below would be an example of adding additional data series to a script,

Below would be an example of how you can have your strategy trade between certain times.

I have also attached 2 strategies which will only trade once per day,

Please let us know if you need further assistance.
