About Net change

[NinjaTrader_ChelseaB]

Hello ラリー,

I believe I was confusing a different thread on a similar topic, linked below.

https://ninjatrader.com/support/forum/forum/ninjatrader-8/indicator-development/1215439-we-want-to-paint-on-the-chart-a-candle-that-has-achieved-at-least-5-from-the-previou?p=1217048#post1217048

Thank you for your reply.

You mentioned the MyNetChangeModifiedNinjaScript file.
Again, I had not yet added the plot, so I added the plot to line 44 in the NinjaScript file and ran it, but there seems to be no change in the market analyzer.

There may have been a problem in the way I communicated this.

I think that the Netchange (percent), which is provided by default in NinjaScript from the beginning, resets after a certain period of time, but I just want to keep it displayed without resetting until 8:00 JST (Japan Standard Time) the next day.

So, you are not wanting to change when the previous close price is set, you just want to get the net change of the day preceding the previous day to the previous day?

In that issue, the net change is the same, but in this case, you want to apply a color (coloring on the individual symbol chart has been resolved, while coloring in the market analyzer has not yet been resolved) to the net change that you arbitrarily specify (e.g., 5%).

So, you are not wanting to change when the previous close price is set, you just want to get the net change of the day preceding the previous day to the previous day?

Also, for this problem, you want to indicate how much net change there was from the previous day's closing price of the individual symbol to the next day's closing price.


Also, I forgot to attach a screenshot of my post 45 thing I posted, so I am attaching it.

Hello ラリー,

The previous day is yesterday. The next day would be today. You want the net change from the previous day (yesterday) to the current price (as the current day would not have ended)?

Thank you for your reply.

For example, let's say the AUDUSD Netchange in the attached image posted in post 35 started trading at 0.20 and ended the day at 0.47%.
I want that displayed 0.47% to remain displayed until the next day (8:00 am, Japan time).
The same applies to the symbol for Japanese stocks.

Hello ラリー,

So you want the net close ending with the previous session close, not the current sessions net close, but the previous one.
(from the day preceding the previous day (2 session ago) close to the previous day close (1 session ago))

Yes, we want it to appear until 8:00 JST the next day.

Hello ラリー,

That would be complex if you want to sort through historical data to measure the netChange and also update in real-time.

In historical, there are a few approaches.

One suggestion, you could use a set of variables to store the current and previous session closes.

private double secondPreviousSessionClose, previousSessionClose;

if(Bars.IsLastBarOfSession)
{
secondPreviousSessionClose = previousSessionClose;
previousSessionClose = Close[0];
return;
}

if (ToTime(Time[0]) < 80000 || ToTime(Time[0]) > 150000) // you can replace the 150000 with whatever time the new session starts
{
CurrentValue = (previousSessionClose - secondPreviousSessionClose);
}

Thank you for your reply.

I will give it a try, but where should I put it (in the screenshot)?

Hello ラリー,

As this would be processing historical data, this would go in OnBarUpdate().

[ラリー]

Thank you for your reply.

I have written the following in OnBarUpdate(), but multiple errors were output.
What was wrong with my description?

Hello ラリー,

Declaring variables (what you have on line 60), should be within the scope of the class, (after the class opening curly brace on likely line 28).

[ラリー]

Thank you for your reply.


I replaced the code in the class and ran it, but MyNetChangeModifled only has 3 horizontal dots and no value (Japanese stock symbol).

Hello ラリー,

Use Print() to understand the behavior.

Print the time of the bar and all values used in the condition.

https://ninjatrader.com/support/forum/forum/ninjatrader-7/strategy-development-aa/99209-date-conditions-not-working?p=791121#post791121

Provide the output saved to at text file.

[ラリー]

Thank you for your reply.

I added a print and performed the run, but after the zero value was output, the decimal value was output.

[NinjaTrader_ChelseaB]

Hello ラリー,

It is important to add labels and time stamps to your prints.

For example:
Print(string.Format("{0} | myValue: {1}", Time[0], myValue));

Further, focus on one item at a time so that the prints are not confused.

If previousSessionClose and secondPreviousSessionClose are both 0, this would mean the condition to set this never evaluated as true.

How many days of historical data is being processed?

May I have you print the time and the value of both Bars.IsFirstBarOfSession and Bars.IsLastBarOfSession above the condition that sets these variables?
