The Average True Range (ATR) is measured in pips. The True Range is the bar height including the gap (if any).
ATR is plotted on the chart as a line. This line can cross a predefined level.
The level is not a part of the indicator, but is used from FSB for calculating the buy or sell signals.
If you use the logic condition "The ATR changes its direction upward", the level is not taken into account from the program. It is significant when you use any of the conditions where the Level is mentioned.
"The ATR is higher than the Level line",
"The ATR is lower than the Level line",
"The ATR crosses the Level line upward",
"The ATR crosses the Level line downward",
The ATR values are shown as price in the chart.
The Level line also is shown as price. It is important to know that the level in pips depends on the broker quotation. A level of 100 pips for a 4 digit quotation is equal to a level of 1000 pips for 5 digit quotation.
The Level on the upper chart is 1000 pips (shown as 0.0100) because the digit = 5.
