The Stop Loss value of an open position changes when the following conditions are met:

1. The value of Parabolic SAR at index 1 is greater/less than the open price (for buy and sell trades respectively);
2. The value of Parabolic SAR at index 1 is less/greater than the Low/High of bar with index 1 (for buy and sell trades respectively);
3. Parabolic SAR on index 1 is formed after the position open time.

The inputs of the utility are:

• base_tf - the timeframe for the Parabolic SAR indicator to be used for trailing Stop Loss;
• SAR_step - price change step (the parameter of "Parabolic SAR", default is 0.1);
• maximum_step - maximum price change (the parameter of "Parabolic SAR", default is 0.11);
