KAB v1.41

The indicator now runs with series indexing, has safer initialization, more robust parameter validation, and a much smarter volatility lock (hysteresis + optional timed release).

In other words, it's more efficient, more reliable, and smarter.

It also gains an option to operate strictly on closed bars to avoid repaint-style behavior on the forming bar.

Although, having said that, repainting is already avoided by a variety of functions:

1. Closed-bar policy

input bool useClosedOnly = false; // use bar-1 at bar 0

2. Use the previous closed bar’s index everywhere the “current” bar is referenced

int piStart = useClosedOnly ? MathMax(start,1) : start;

int pi = useClosedOnly ? MathMax(i,1) : i;

3. All state/price lookbacks use only prior closes

double sATR = CalcTR(high[piStart], low[piStart], close[piStart+1]);

double tr = CalcTR(high[pi], low[pi], close[pi+1]);

double unsm = prev + alpha * (close[pi] - prev);

4. Seed/recursion is strictly causal (each bar depends only on the previous output)

if(prev_calculated == 0) m_kabBuffer[start] = close[piStart];

double prev = (i==start ? m_kabBuffer[i] : m_kabBuffer[i+1]);


KAB is context-aware where traditional Moving Averages are static. When choosing a baseline, choose KAB.
