Simple Modifications of Internal Bar Strength Indicator (+ MA + ROC)

==Description==

I have an IBS indicator which requires some additions to make it like the one I use in TV:

Moving average of Internal Bar Strength

* This is a very decent entry and exit indicator

* Would like to be able to take IBS as substrate for an EMA or SMA of configurable length (default=5)

Rate Of Change of Internal Bar Strength

* This is decent indicator for finding reversals

* This will also need to be length configurable (default=5)

Visuals

These can all just represent as lines with configurable upper and lower bound thresholds (configurable)... see below:

Here's the same in Pinescript  ...

//@version=5
indicator(title="InternalBarStrength-DK", shorttitle="InternalBarStrength-DK", overlay=false, timeframe="", timeframe_gaps=true)

// up candle (= normal IBS) 
mibs = (close - low) / (high - low)

// down candle (= reverse IBS)
if (close - open) < 0
    mibs := (high - close) / (high - low)
//plot(mibs, title="IBS Up/Down", color=#7E57C2)

// normal IBS (secondary plot slight blue)
// normal IBS1 (secondary plot slight blue)
cibs = (close - low) / (high - low)
plot(cibs, title="cibs", color=color.rgb(41, 98, 255, 4))
oibs = (open - low) / (high - low)
plot(oibs, title="oibs", color=color.rgb(255, 251, 41, 4))
cibsema = ta.ema(cibs,5)
plot(cibsema, title="cibsema", color=color.rgb(230, 16, 8, 4))
// Calculate the rate of change (ROC)
cibsroc_length = 5  // Number of bars for comparison
cibsemaroc = (cibsema - cibsema[cibsroc_length]) / cibsema[cibsroc_length]

// Plot the ROC
plot(cibsemaroc, title="Rate of Change of MA", color=color.rgb(218, 23, 201))


// bands
band_upper = hline(0.80, "Upper Band", color = #787B86)
band_lower = hline(0.20, "Lower Band",  color = #787B86)
fill(band_upper, band_lower, color=color.rgb(126, 87, 194, 90), title="Background Fill")
