Convert T3 Bands Indicator from MT5 to ThinkorSwim?

[ryan]

Wondering anyone can help the following mt5 indicator to tos?

Thanks!

input int      inpPeriod        = 15;            // Period
input int      inpT3Period      = 5;             // T3 period
input double   inpT3Hot         = 0.7;           // T3 hot
input enT3Type inpT3Type        = t3_fulksmat;   // T3 type
input double   inpLevels        = 100;           // Levels at +- (nnn)
