Specification

Please convert the 2 Pine Scripts below into MQL5 Indicator, it has to be done in 2 days:

1. RMD

//@version=5
indicator('Ranging Market Detector', shorttitle='RMD')

// input paraneters
treshold_level = input.float(title='treshold', defval=4, minval=0, step=1)

//Kalman filter calculation
p = ohlc4

value1 = 0.0
value2 = 0.0
klmf = 0.0

value1 := 0.2 * (p - p[1]) + 0.8 * nz(value1[1])
value2 := 0.1 * (high - low) + 0.8 * nz(value2[1])
lambda = math.abs(value1 / value2)

alpha = (-lambda * lambda + math.sqrt(lambda * lambda * lambda * lambda + 16 * lambda * lambda)) / 8
klmf := alpha * p + (1 - alpha) * nz(klmf[1])


// Calculateing the absolute value of the Kalman filter curve slope
klmf_diff = math.abs(klmf - klmf[1])

// Long term average of the Kalman filter slope
av_klmf_diff = 1.0 * ta.ema(klmf_diff, 200)

// The Kalman filter slope minus the average slope (Decline from the average slope)
// This slope decline is divided by the average slope value to normalize it
normalized_slope_decline = (klmf_diff - av_klmf_diff) / av_klmf_diff

// Condition that defines the trend regime
// Slope declined from the average by not less than the given treshold value
trend_condition = (normalized_slope_decline >= treshold_level) or (normalized_slope_decline[1] >= treshold_level)

bgcol = trend_condition ? color.new(color.yellow, 30) : color.new(color.gray, 30)
// Plot normalized slope decline as histogram plot
plot(normalized_slope_decline, style=plot.style_columns, color=bgcol, linewidth=3)
//plot(lambda, style=plot.style_histogram, color=color.new(color.blue, 0), linewidth=3)
// Plot treshold level line
plot(treshold_level, color=color.new(color.yellow, 0))


2. HalfTrend

//@version=5
indicator('HalfTrend', overlay=true)

amplitude = input(title='Amplitude', defval=1)

channelDeviation = 2
atr_input = 100
showArrows = true
showChannels = true

var int trend = 0
var int nextTrend = 0
var float maxLowPrice = nz(low[1], low)
var float minHighPrice = nz(high[1], high)

var float up = 0.0
var float down = 0.0
float atrHigh = 0.0
float atrLow = 0.0
float arrowUp = na
float arrowDown = na

atr2 = ta.atr(atr_input) / 2
dev = channelDeviation * atr2

highPrice = high[math.abs(ta.highestbars(amplitude))]
lowPrice = low[math.abs(ta.lowestbars(amplitude))]
highma = ta.ema(high, amplitude)
lowma = ta.ema(low, amplitude)

if nextTrend == 1
    maxLowPrice := math.max(lowPrice, maxLowPrice)

    if highma < maxLowPrice and close < nz(low[1], low)
        trend := 1
        nextTrend := 0
        minHighPrice := highPrice
        minHighPrice
else
    minHighPrice := math.min(highPrice, minHighPrice)

    if lowma > minHighPrice and close > nz(high[1], high)
        trend := 0
        nextTrend := 1
        maxLowPrice := lowPrice
        maxLowPrice

if trend == 0
    if not na(trend[1]) and trend[1] != 0
        up := na(down[1]) ? down : down[1]
        arrowUp := up - atr2
        arrowUp
    else
        up := na(up[1]) ? maxLowPrice : math.max(maxLowPrice, up[1])
        up
    atrHigh := up + dev
    atrLow := up - dev
    atrLow
else
    if not na(trend[1]) and trend[1] != 1
        down := na(up[1]) ? up : up[1]
        arrowDown := down + atr2
        arrowDown
    else
        down := na(down[1]) ? minHighPrice : math.min(minHighPrice, down[1])
        down
    atrHigh := down + dev
    atrLow := down - dev
    atrLow

ht = trend == 0 ? up : down

var color buyColor = color.blue
var color sellColor = color.red

htColor = trend == 0 ? buyColor : sellColor
htPlot = plot(ht, title='HalfTrend', linewidth=2, color=htColor)
