Welcome to Baby Pips
have you done the school? If not work your way through it many of your question will be answered.
A HL or LH
Its just what it sounds like. A higher low is a swing low that is higher up the chart then the last swing low. A swing low is a point that is lower then price immediately before and after that point. You can not define a swing point as it happens its only apparent after some time has passed. A Bill Williams Fractal will show you a swing point generally. The Fractal indicator that comes with MT4 will draw fractals on your chart. A Fractal is a 5 candle pattern a Fractal can not be established until the 3rd candle after the low or high point. If you put the indicator on a 1 min chart you will see the indicator appear and disappear as the chart moves. Once an arrow has stayed on the chart for 2 candles it will not disappear. This is called repainting.
On this gap open we see a bull trap set by bears trying to eat raccoons in the upward secondary tick pattern that is divergent to our Proprietary order flow indicator. You can see the x rated exhaustion level by which all of the sheep will be pulled in and sheared by the smart money
