# Hull HAMA Wave Indicator for ThinkorSwim

A user on the Discord server, Brandon_L, sent in this cool indicator. As he explains, the HAMA indicator was popularized by Brian Watt and Cid Da Silva, it changes in height to measure severity of trends.

He messaged me with a question about some kind of indicator which changed color when the length of the wicks/candle of the HAMA changed.

Here are the couple iterations that I came up with.

### HAMA Lower Study

Code:
declare lower;

input period = 21;
input hideCandles = NO;
input candleSmoothing = {default Valcu, Vervoort};

DefineGlobalColor("RisingMA", color.uptick);
DefineGlobalColor("FallingMA", color.downtick);

input movingAverageType = {default TEMA, Exponential, Weighted, Hull, Variable, SIMPLE};

def lowMA;

switch (movingAverageType) {

Honorable mentions: I prefer the hull HAMA and it fits nicely with either the TMO or the DPO MOBO.

OMG! Yes I'm a huge fan of @rad14733 DPO MOBO and this HULL HAMA will be the second lower indicator I've been searching for!
