how to get volatility of last bar

in PEL, if i want to compare volatility of current bar with last bar, how do i code it?
do i have to add volatility as input or there is something like volatility(length) > volatility(length)[-1]

thanks

Hello martingale,

Check if the prebuilt Volatility function works for your calculation.
Store the value it calculates on each bar in a variable and compare the current variable value with the previous one.

hi Henry
prebuilt volatility function works,
how to store them in each bar and reference the value in next bar?
thanks

martingale,

you can store the function's return value in a variable and use this variable within your code.

is the vVolatility an array or just a scalar value in this case?
if i'd refer to vVolatility value of 10 bars ago, i can just use vVolatility(-10)?

thanks

Code: Select all

Input: Length( 14 ) ; Variable: vVolatility( 0 ); vVolatility = Volatility( Length ) ; Plot1( vVolatility, "Volatility" ) ;

martingale,

vVolatility is a variable and you can back reference previous bar's values for variables using a number in square brackets.

vVolatility[0] is the value on the current bar (although [0] is usually omitted), vVolatility[1] is the value one bar to the left of the current bar etc..
