GetEma return NULL about stock.indicators HOT 2 CLOSED

In this scenario, there are cumulative incalculable warmup periods for EMA, so the first preSmoothLength + postSmoothLength - 2 periods returned in postEmaClose will be null. For just preEmaClose you should see preSmoothLength - 1 initial values that are null.

• Example: https://dotnetfiddle.net/3tkEzb

mathematically incalculable periods:

• 0 for Heiken-Ashi
• N-1 for each Exponential Moving Average (EMA)

Is that what you're seeing?
If you post your raw price quotes and lookbackPeriods values, I'll take a look and see if I can replicate.

side note: you'll also see a longer period where precision accuracy converges, approximately preSmoothLength + postSmoothLength + 100 periods in this case.
