South African Rand looking horrid target to R18.40

Falling Wedge formed on USD/ZAR
7>21>200 -BUllish
RSI >50
With the Jobs data coming out much better than expected, and with the rising interest rates - this seems to have a positive effect on the US dollar as investors are putting their money in it.
The economy is clearly booming and earnings are coming out better than expected.
My first target for the USD/ZAR is R18.40
