Hi, I am looking for someone to help me to find or create the following indicator from TradingView to Mql5.
The indicator is Relative Volatility Index, it is necessary that it comes out as in tradingview, that is to say with its SMA and with the modification of periods.
I copy from the TradingView source code:
//@version=5
indicator(title="Relative Volatility Index", shorttitle="RVI", format=format.price, precision=2, timeframe="", timeframe_gaps=true)
length = input.int(10, minval=1)
offset = input.int(0, "Offset", minval = -500, maxval = 500)
maTypeInput = input.string("SMA", title="MA Type", options=["SMA", "Bollinger Bands", "EMA", "SMMA (RMA)", "WMA", "VWMA"], group="MA Settings")
maLengthInput = input.int(14, title="MA Length", group="MA Settings")
bbMultInput = input.float(2.0, minval=0.001, maxval=50, title="BB StdDev", group="MA Settings")
src = close
len = 14
stddev = ta.stdev(src, length)
upper = ta.ema(ta.change(src) <= 0 ? 0 : stddev, len)
lower = ta.ema(ta.change(src) > 0 ? 0 : stddev, len)
rvi = upper / (upper + lower) * 100
ma(source, length, type) =>
switch type
"SMA" => [ta.sma(source, length), na, na]
"Bollinger Bands" =>
[middleValue, highValue, lowValue] = ta.bb(source, length, bbMultInput)
[middleValue, highValue, lowValue]
"EMA" => [ta.ema(source, length), na, na]
"SMMA (RMA)" => [ta.rma(source, length), na, na]
"WMA" => [ta.wma(source, length), na, na]
"VWMA" => [ta.vwma(source, length), na, na]
[rviMA,highValue,lowValue] = ma(rvi, maLengthInput, maTypeInput)
h0 = hline(80, "Upper Band", color=#787B86)
hline(50, "Middle Band", color=color.new(#787B86, 50))
h1 = hline(20, "Lower Band", color=#787B86)
fill(h0, h1, color=color.rgb(126, 87, 194, 90), title="Background")
plot(rvi, title="RVI", color=#7E57C2, offset = offset)
plot(rviMA, "RVI-based MA", color=color.yellow, offset = offset)
bbUpper = plot(highValue, title="Upper Bollinger Band", color=color.green)
bbLower = plot(lowValue, title="Lower Bollinger Band", color=color.green)
fill(bbUpper, bbLower, color = color.new(color.green, 90), title="Bollinger Bands Background Fill")
