my wife use some kind of indicator(she does not tell me what kind of indicator it is) which shows a range on the chart. based on her past experience, it kiss the botttom line and touch the top line quite accurately. the middle line is something called POC (price of control?). Due to she is more conservative than I am, she choose the middle line, otherwise, I would choose the top line which might be close to 33 Bro's exit price.
