Hi,

Could someone please help translate this code from trading view into think or swim?

//@version=3

thirtyrsi = iff( x1 >= 0, close + x1, close + x1 * (100-thirty)/thirty )

x7 = (length - 1) * ( adc * seventy / (100-seventy) - auc)

@Ahmar824 If I haven't said this earlier, I am saying it now, Always love your video and explanation of what you need and what you found. This is very helpful. 😍

Now to the matter at hand, I have customized the code for you, so your can set the band High and Low to what you want, not that 60-40 isn't great.

Below Code is for chart frame with labels.

Ruby: 
#RSI_BAND
#Convered by @SuryaKiranC
#Reqested by @kd312
# https://usethinkscript.com/threads/convert-rsi-from-tradingview.9346/

input length = 14;
input high_B = 60;
def    mid_B = 50;
input  low_B = 40;

def ep = 2 * length - 1;

def auc = ExpAverage(max (close - close[1],0),ep);
def adc = ExpAverage(max (close[1] - close,0),ep);

def x1 = (length - 1) * (adc * low_B / (100-low_B) - auc);
plot lowrsi = if(x1 >= 0, close + x1, close + x1 * (100 - low_B)/low_B);
lowrsi.SetDefaultColor(CreateColor(0, 255, 0));

def x7 = (length - 1) * (adc * high_B / (100-high_B) - auc);
plot highrsi = if(x7 >= 0, close + x7, close + x7 * (100-high_B)/high_B);
highrsi.SetDefaultColor(CreateColor(82, 128, 233));

def x13 = (length - 1) * (adc * mid_B / (100-mid_B) - auc);
plot midrsi = if(x13 >= 0, close + x13, close + x13 * (100-mid_B)/mid_B);
midrsi.SetDefaultColor(CreateColor(254, 3, 1));

plot DClose = close(period = "DAY");
DClose.SetPaintingStrategy(PaintingStrategy.DASHES);

AddLabel(!isNan(midrsi),if GetAggregationPeriod() == aggregationPeriod.MONTH then "M"
else if GetAggregationPeriod() == aggregationPeriod.WEEK then "W"
else if GetAggregationPeriod() == aggregationPeriod.FOUR_DAYS then "4D"
else if GetAggregationPeriod() == aggregationPeriod.THREE_DAYS then "3D"
else if GetAggregationPeriod() == aggregationPeriod.TWO_DAYS then "2D"
else if GetAggregationPeriod() == aggregationPeriod.DAY then "D"
else if GetAggregationPeriod() == aggregationPeriod.FOUR_HOURS then "4H"
else if GetAggregationPeriod() == aggregationPeriod.TWO_HOURS then "2H"
else if GetAggregationPeriod() == aggregationPeriod.HOUR then "60m"
else if GetAggregationPeriod() == aggregationPeriod.THIRTY_MIN then "30m"
else if GetAggregationPeriod() == aggregationPeriod.TWENTY_MIN then "20m"

else if GetAggregationPeriod() == aggregationPeriod.FOUR_MIN then "4m"
else if GetAggregationPeriod() == aggregationPeriod.THREE_MIN then "3m"
else if GetAggregationPeriod() == aggregationPeriod.TWO_MIN then "2m"
else if GetAggregationPeriod() == aggregationPeriod.MIN then "1m"
else "",Color.GRAY);
AddLabel(yes,highrsi + " ",(CreateColor(82, 128, 233)));
AddLabel(yes,midrsi + " ",(CreateColor(254, 3, 1)));
AddLabel(yes,lowrsi + " ",(CreateColor(0, 255, 0)));
#End

To address another matter, for the higherFrames labels only, Would you be willing to add 2nd script, multiple times, depends on how many higher frames you want to see? if so here is the code, Just add and set each instance of the code to a different frame, only chart frame and higher will display labels.

input length = 14;

input high_B = 60;
def    mid_B = 50;
input  low_B = 40;

input aP = AggregationPeriod.FIFTEEN_MIN;

Script RSI_BAND {
input length = 14;

input high_B = 60;
def    mid_B = 50;
input  low_B = 40;

input aP = AggregationPeriod.FIFTEEN_MIN;

def ep = 2 * length - 1;

def auc = ExpAverage(max(close(period = aP) - close(period = aP)[1],0),ep);
def adc = ExpAverage(max(close(period = aP)[1] - close(period = aP),0),ep);

def x1 = (length - 1) * (adc * low_B / (100 - low_B) - auc);
plot lowrsi = if(x1 >= 0, close(period = aP) + x1, close(period = aP) + x1 * (100-low_B)/low_B);

plot highrsi = if(x7 >= 0, close(period = aP) + x7, close(period = aP) + x7 * (100-high_B)/high_B);

def x13 = (length - 1) * (adc * mid_B / (100-mid_B) - auc);
plot  midrsi = if(x13 >= 0, close(period = aP) + x13, close(period = aP) + x13 * (100 - mid_B)/mid_B);

};

def highrsi = RSI_BAND(length = length,high_B = high_B,low_B = low_B,aP = aP).highrsi;
def  midrsi = RSI_BAND(length = length,high_B = high_B,low_B = low_B,aP = aP).midrsi;
def  lowrsi = RSI_BAND(length = length,high_B = high_B,low_B = low_B,aP = aP).lowrsi;

AddLabel(!isNan(midrsi),if aP == aggregationPeriod.MONTH then "M"
else if aP == aggregationPeriod.WEEK then "W"
else if aP == aggregationPeriod.FOUR_DAYS then "4D"
else if aP == aggregationPeriod.THREE_DAYS then "3D"
else if aP == aggregationPeriod.TWO_DAYS then "2D"
else if aP == aggregationPeriod.DAY then "D"
else if aP == aggregationPeriod.FOUR_HOURS then "4H"
else if aP == aggregationPeriod.TWO_HOURS then "2H"
else if aP == aggregationPeriod.HOUR then "60m"
else if aP == aggregationPeriod.THIRTY_MIN then "30m"
else if aP == aggregationPeriod.TWENTY_MIN then "20m"
else if aP == aggregationPeriod.FIFTEEN_MIN then "15m"
else if aP == aggregationPeriod.TEN_MIN then "10m"
else if aP == aggregationPeriod.FIVE_MIN then "5m"
else if aP == aggregationPeriod.FOUR_MIN then "4m"
else if aP == aggregationPeriod.THREE_MIN then "3m"
else if aP == aggregationPeriod.TWO_MIN then "2m"
else if aP == aggregationPeriod.MIN then "1m"
else "",Color.GRAY);
AddLabel(yes,highrsi + " ",(CreateColor(82, 128, 233)));
AddLabel(yes,midrsi + " ",(CreateColor(254, 3, 1)));
AddLabel(yes,lowrsi + " ",(CreateColor(0, 255, 0)));
#End

Now, when you get a chance, can you test this RSI_BAND 60-40 on 15m and/or 30m frames? My interest in those frames are the 30m being th last frame that can divide the trading hours candles equally for equity, and 15 for some ETF that trades extra 15m.

If someone wants to change the 70 to 75 let's say they don't have to change anything else right?
 
Hello, Does anyone have an RSI indicator that also have a bollinger band in it for thinkorswim and is willing to share? I found the below code on Tradingview
https://www.tradingview.com/script/nYocl0iB-RSI-with-Bollinger-Bands-Erionis/
that does come with one but I don't use Tradingview anymore. Or, If someone could convert this to Thinkorswim please, I will really appreciate it. Thanks a ton!
