Volatility for all parameters nominated in points

What is a “point” in CommunityPower EA?

Starting from v2.31, you can set Volatility for all parameters nominated in points, as well as limit volatility min and max size:

Then you can set calculation mode for any parameter to Volatility Coefficient:

In this example, TrailingStop size will be calculated as ATR * 1.5, and Trailing Step will be ATR * 0.1.

Calculation mode is available for almost all parameters in the EA.


Percentage of Price

Starting from v3.0.15, you can choose Percentage of Price calculation mode: distance will be calculated as asset price * Percentage / 100.

Asset price is usually series average open price or order open price (for Individual Follow-up and Pending orders).


Volatility Indicator

Indicator used for the Volatility calculation. Can be one of the following:

  • ATR
  • StDev
  • ATR (Close-Open): average candle body size (abs(Close - Open)) for the last N bars
  • WATR
  • Volume (don’t use for this block!)
  • OBV (don’t use for this block!)
  • Price Range: highest high - lowest low for the last N bars
  • Percent Change: average change (abs(close_curr - close_prev)) for the last N bars


TimeFrame and Period

TimeFrame and Period of volatility indicator


Invert/Smooth Period

(starting from v3.0.15)

If Invert/Smooth Period > 0, indicator value will be inverted against the MA with this period based on the indicator value.

For example, if Invert/Smooth Period = 5, MA(5) will be applied to the indicator value, and the final value will be calculated as MA(5) - (indicator value - MA(5)).

If Invert/Smooth Period < 0, indicator value will be smoothed with the MA with this period.

For example, if Invert/Smooth Period = -5, MA(5) will be applied to the indicator value, and the final value will be equal to MA(5).

To understand this parameter better, you can use the iVolatility indicator: for MT4 and for MT5.


Min and Max volatility to use (points)

Indicator value will be limited by these Min and Max values defined in Points (what is a “point”?).

For example, if current StDev value is 0.00203 (20.3 points for EURUSD), and you set Min volatility to use = 25, EA will use 25 points as volatility size (and TrailingStop with Volatility Coefficient = 1.5 will be 25 * 1.5 = 37.5 points (not 20.3 * 1.5 = 30.45)).

Set 0 to disable the limit.


Min volatility to use (spreads)

(starting from v3.0.15)

Indicator value will be limited by this Min value defined as a number of ‘normal’ spreads.

For example, if current StDev value is 0.00203 (20.3 points for EURUSD), and current ‘normal’ spread is 1.5 points, and you set Min volatility to use (spreads) = 20, EA will use 20 * 1.5 = 30 points as volatility size (and TrailingStop with Volatility Coefficient = 1.5 will be 30 * 1.5 = 45 points (not 20.3 * 1.5 = 30.45)).

Set 0 to disable the limit.


Fix at the 1st position opening

(starting from v2.50)

Set true to use the same volatility over the lifetime of the series.

Set false to refresh volatility every bar.
