Technical Indicator Relative Strength Index (Relative
Strength Index (RSI) is an oscillator following the price, which
ranges from 0 to 100. Values below 30 are considered an oversold zone, values above 70 are considered an overbought zone. The classic interpretation of the readings is as follows: when the oscillator line exits the oversold zone, a signal appears to open a long position, and when it exits the overbought zone, a short one appears.

The indicator displays the position opening points as arrows on the chart.  

Input parameters:

• Period RSI – period of the RSI indicator;
• Signal level in percent – the level that the line must cross in order to receive a signal to open a position.

Condition for opening a long position (green up arrow): the line crosses the Signal level in percent from the bottom up.

Condition for opening a short position (red down arrow): the line crosses from top to bottom the level 100-Signal level in percent, for example, if the default value of Signal level in percent is 30, this value will be 70.
