systems on Heiken Ashi candlesticks. You can select one of its three versions: Standard Old Standard New and Fibo.

Purpose

The indicator can be used for manual or automated trading in an Expert Advisor. Values of indicator buffers of the double type can be
used for automated trading:

1. Pivot Point – buffer 0.
2. Support level 1 – buffer 1.
3. Support level 2 – buffer 2.
4. Support level 3 – buffer 3.
5. Resistance level 1 – buffer 4.
6. Resistance level 2 – buffer 5.
7. Resistance level 3 – buffer 6.

Depending on the timeframe of the chart, on which the indicator is used, values of the indicator buffers towards the depth of the history should be
requested with a shift relative to the zero bar and the same step on the following principle:

1. PERIOD_M1: the shift and the step = 1440.
2. PERIOD_M5: the shift and the step = 288.
3. PERIOD_M15: the shift and the step = 96.
4. PERIOD_M30: the shift and the step = 48.
5. PERIOD_H1: the shift and the step = 24.
6. PERIOD_H4: the shift and the step = 6.
7. PERIOD_D1: the shift and the step = 1.

Limitations

Chart for each financial instrument can not be displayed more than once. Otherwise, you will receive an error message related to its re-use and
you will be offered to select another financial instrument.

Recommendations

It is recommended to use the indicator with the parameter Bars_Number not exceeding the number of bars that can be shown in one window (about
250 bars).
