I'm using a for loop that goes through a series of datapoints and works out how to class the trend that the data is showing
Here's the logic to flag the points:
- If 6 points in a row have a decreasing/increasing trend, flag as "Decreasing Trend"/"Increasing Trend"
- else if 7 points in a row are below/above the mean, flag as "Below Mean"/"Above Mean"
We prioritising the increasing/decreasing trend over below or above the mean
I think the logic i'm using is incorrect, but i'm unsure why. This is some of the logic in a sentence for the series:
"For each point, if the next 5 points are below this and then their previous partner, mark all those points as 'Decreasing Trend'. Else if a point isn't trend marked, see if the following 6 points from this point are all above or below the mean"
You can copy and paste this in in totality:
package main
import (
"bufio"
"fmt"
"os"
"strings"
)
type points struct {
quantity float64
lowerBound float64
upperBound float64
mean float64
pattern string
}
func main() {
var pointsToUse = []points{
points{quantity: 3.5, lowerBound: 1, upperBound: 4.8,, mean: 4, pattern: "Common Variation"},

The output that I need to show is this:
3.50 | Decreasing Trend
3.40 | Decreasing Trend
3.20 | Decreasing Trend
3.19 | Decreasing Trend
3.17 | Decreasing Trend
3.14 | Decreasing Trend
3.12 | Decreasing Trend
3.09 | Decreasing Trend
4.1 | Common Variation
3.16 | Below Mean
3.00 | Below Mean
3.00 | Below Mean
3.11 | Below Mean
3.12 | Below Mean
3.14 | Below Mean
3.13 | Below Mean
3.17 | Below Mean
Can someone identify where i'm going wrong?
