see script below

I am trying to make my TOS look like my MT4 chart. There is a free MT4 indicator MACD indicator that I use, I was able to find an exact match for it on Tradingview and have been looking for a possible code for TOS. I tried using ChatGPT to convert it but it keeps giving me new scripts but all have errors and are useless. Can anyone help convert this free indicator code from pinescript to thinkscript.

slowMA = input(title="Slow moving average", type = input.integer, defval = 26, minval = 7)
signalLength = input(9, "Signal Length", minval=1)

[currMacd,_,_] = macd(close[0], fastMA, slowMA, 9)
[prevMacd,_,_] = macd(close[1], fastMA, slowMA, 9)

signal = sma(currMacd, signalLength)
plotColor = currMacd > 0 ? currMacd > prevMacd ? color.lime : color.green : currMacd < prevMacd ? color.maroon : color.red
plot(currMacd, style = plot.style_columns, transp=20, color = plotColor, linewidth = 3, title="Macd Bars")
plot(signal, color=color.white, transp=0, title="Macd Signal")
