Price High Low
The high low indicator is one of the most simple and stable indicators.
The Static High/Low is simple. Simply put in your buy price and sell price. You can put your prices near the current price or farther away. For example, if the current price is 100$ you could enter BUY: 95.25$ and SELL: 104.89$. Of course, if the market breaks out in either direction, then you will have to recalculate your values, as with all static indicators and safeties.
Dynamic High/Low works in the same way as the static one, just that it recalculates the Buy and Sell thresholds itself. You set the size of data that is used to determine a high and low price and the update time. The longer the update time the less trades but the profit per trade should be higher.
