Ceiling line not working with minimum
-
Hi,
Let’s take an ema and compare current value with its previous value.
As long as it goes down, slode negative, we draw a ceiling on top of price with highest high of last 20 bars.
ema = Average[20](close) IF ema < ema[1] THEN ceils = Highest[20](high) ELSE ceils = ceils[1] ENDIF Return ceilsResult in attached file.
It looks great until the slope turns positive for a few candles, and then negative again, whereas during these few candles the highhest high over the 20 last high has increased.
The orange line turns blue. But I don’t want the ceiling value to increase.
So I decide, when the slope is negative, to draw as ceiling the minimum value beetween the previous ceilling and the highest high.
ema = Average[20](close) IF ema < ema[1] THEN ceils = Min(ceils[1], Highest[20](high)) ELSE ceils = ceils[1] ENDIF Return ceilsWhen I validate the indicator, no ceiling line is drawn on the chart.
I don’t undestrand why …
I tried to initialise with a high value, and/or use a temporary variable to calculate the min …
ema = Average[20](close) once ceils = 1000000000000000 IF ema < ema[1] THEN k = Min(ceils[1], Highest[20](high)) ceils = k ELSE ceils = ceils[1] ENDIF Return ceilsCeiling line still not drawn on chart 🙂
Any idea why ?
Thks.
