### Senkou Span A

This study calculates and displays the Senkou Span A for the Price Data.

Let $$H$$ and $$L$$ be random variables denoting the High and Low Prices, respectively, and let $$H_t$$ and $$L_t$$ be their respective values at Index $$t$$. Let the Tenkan-Sen Length and Kijun-Sen Length Inputs be denoted as $$n_{TS}$$ and $$n_{KS}$$, respectively. Then we denote the Senkou Span A at Index $$t$$ for the given Inputs as $$SSA_t(n_{TS},n_{KS})$$, and we compute it in terms of Tenkan-Sen and Kijun-Sen for $$t \geq 0$$ as follows.

$$\displaystyle{SSA_t(n_{TS},n_{KS}) = \frac{TS_t(H,L,n_{TS}) + KS_t(H,L,n_{KS})}{2}}$$

Note: Senkou Span A by default has a Displacement setting of 26. When changing the various Input settings for this study, you may need to change the Displacement setting as needed.
