Please explain why the Indicator with no Inputs: does not print the var0 value correctly and the one with Inputs does. Thank you
------Var0 only prints 50-------------------
variables: Price( Close ),Length( 9 );
variables: var0(0);
var0 = RSI( Price, Length ) ;
print("RSI:",var0);
------Var0 prints correct chart values------
Inputs: Price( Close ),Length( 9 );
variables: var0( 0 ) ;
var0 = RSI( Price, Length ) ;
print("RSI:",var0);

Please explain why the Indicator with no Inputs: does not print the var0 value correctly and the one with Inputs does. Thank you ------Var0 only prints 50------------------- variables: Price( Close ),Length( 9 ); variables: var0(0); var0 = RSI( Price, Length ) ; print("RSI:",var0); ------Var0 prints correct chart values------ Inputs: Price( Close ),Length( 9 ); variables: var0( 0 ) ; var0 = RSI( Price, Length ) ; print("RSI:",var0);

When defining Inputs, the value is automatically updated on every bar. Therefore, using an input of Price(Close), the Price variable will always hold the closing price of the latest bar.

When defining Variables, the value is not automatically updated on every bar. So when the indicator initially runs, it assigns the variable an initial value, but this value is never updated. You will have to update the variable in order for this to work.

 

Code

variables: Price( Close ),Length( 9 ); variables: var0(0); // add this line to update variable value Price=Close; var0 = RSI( Price, Length ) ; print("RSI:",var0);
