Simple conversion from NT7 does not work

[newbe17]

A simple indicator shows completely different values on NT7 and NT8

Where did I go wrong?

Hello newbe17,

The NinjaTrader 7 chart is 3 second 03-21 chart the NinjaTrader 8 chart is a 1 minute 09-21 chart. Different data will produce different results.

Further, in NinjaTrader 7 when no value is set, the close price is used instead which can change the calculations. In NinjaTrader 8 when no value is set a 0 is returned.

Use prints to understand the behavior. Print the time and print all values used for the calculations being set to that plot.
For example where DownTrend is set:

DownTrend[0]=Low[0]-TickSize;
Print(string.Format("{0} | Low[0]: {1}, TickSize: {2}, Low[0]-TickSize: {3}", Time[0], Low[0], TickSize, Low[0]-TickSize));

Below is a link to a forum post that demonstrates using prints to understand behavior.

Hello newbe17,

Then how do I get the same values in NT8 as in NT7?

if (DownTrend.IsValidDataPoint(1))
_trend[0]=(Close[0] > DownTrend[1]);
else
_trend[0]=(Close[0] > Close[1]);

Hello newbe17,

Start by using prints to confirm what is causing differences. Print the time of the bar and all values involved with that plot. Address the value that is different.

Use <Series>.IsValidDataPoint() to check if a value has been set, and choose what value to use when no value is set.
