Hull Trend with Cloud

לפני 5 שעות

This script is designed to plot two Hull Moving Averages (HMAs) and create a cloud between them, which changes color based on the trend. Here's a breakdown of what each part of the script does:

### Script Breakdown

1. **Indicator Declaration**
```pinescript
//version=5
indicator("Hull Trend with Cloud", shorttitle="HMA Cloud", overlay=true)
```
This line declares the script as a Pine Script version 5 indicator with the title "Hull Trend with Cloud" and a short title "HMA Cloud". The `overlay=true` parameter means the indicator will be plotted on the price chart.

2. **Input Parameters**
```pinescript
length1 = input.int(20, title="HMA 1 Length")
length2 = input.int(50, title="HMA 2 Length")
src = input.source(close, title="Source")
showcross = input.bool(true, title="Show cross over/under")
```
These lines define input parameters for the script:
- `length1` and `length2` are the lengths for the two HMAs.
- `src` is the data source for the HMAs, defaulting to the closing price.
- `showcross` is a boolean input to toggle the display of crossover signals.

3. **Calculate HMAs**
```pinescript
hma1 = ta.hma(src, length1)
hma2 = ta.hma(src, length2)
```
These lines calculate the two HMAs using the specified lengths.

4. **Determine Trend Direction**
```pinescript
hup = hma1 > hma1[1]
hdwn = hma1 < hma1[1]
```
These lines determine if the 20-period HMA (`hma1`) is trending up or down by comparing its current value to its previous value.

5. **Set HMA Color Based on Trend**
```pinescript
hmycolor = hup ? color.rgb(13, 235, 128) : hdwn ? color.rgb(211, 42, 19) : na
plotHMA1 = plot(hma1, color=hmycolor, linewidth=2)
plotHMA2 = plot(hma2, color=color.orange, linewidth=2)
```
These lines set the color of the 20-period HMA based on its trend direction:
- Green if trending up.
- Red if trending down.
- The 50-period HMA is plotted in orange.

6. **Create Cloud Between HMAs**
```pinescript
colorCloud = hma1 > hma2 ? color.green : color.red
fill(plotHMA1, plotHMA2, color=colorCloud, transp=75)
```
This section creates a cloud between the two HMAs:
- Green if the 20-period HMA is above the 50-period HMA.
- Red if the 20-period HMA is below the 50-period HMA.

7. **Crossover Signals**
```pinescript
crossup = ta.crossover(hma1, hma1[1])
crossdn = ta.crossunder(hma1, hma1[1])
```
These lines detect crossovers of the 20-period HMA with its previous value to generate buy and sell signals.

8. **Plot Buy and Sell Signals**
```pinescript
plotshape(series=showcross and crossup ? hma1 : na, location=location.belowbar, style=shape.labelup, color=color.green, size=size.small, text="Buy", textcolor=color.white)
plotshape(series=showcross and crossdn ? hma1 : na, location=location.abovebar, style=shape.labeldown, color=color.red, size=size.small, text="Sell", textcolor=color.white)
```
These lines plot buy and sell signals on the chart based on the crossover conditions.

### Summary
This script plots two Hull Moving Averages (20-period and 50-period) and creates a cloud between them that changes color based on the trend. It also generates buy and sell signals based on the crossover of the 20-period HMA with its previous value.
