# Volatility for all parameters nominated in points

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 **Coefficient to Volatility**:

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

You can set “calculation mode” for the following parameters:

- Pending entry: Distance to order and Cancel after distance
- StopLoss size
- TakeProfit size
- Min profit to close on signal
- Martingale Step size
- Anti-martingale Step size
- Anti-StopLoss size
- TrailingStop size
- Trailing Step
- Start trailing after

### Volatility Indicator

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

- ATR
- StDev
- ATR based on “Close-Open” (high and low prices not used)
- WATR
- Volume (don’t use for this block!)

### TimeFrame and Period

TimeFrame and Period of volatility indicator

### 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 coefficient to volatility = 1.5 will be 25 * 1.5 = 37.5 points (not 20.3 * 1.5 = 30.45).

Set 0 to disable the limit.

### Fix volatility on 1st position open

^{(starting from v2.50)}

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

Set **false** to refresh volatility every bar.
