user variable in strategy wizard

[balucang]

Hi guys,
I am new to the forum and just starting to get familiar with strategy wizard and ninja's editor.
I have defined the following inputs:
n= number of lookback bars
bx= percentage multiplier of range

I've then defined variable0 as being the Range over the last n bars using the indicator "Range".

I would like to buy when the current price (c) crosses over c+bx*variable0

How can I define in the wizard a new variable1=c+bx*variable0?

If not possible from the wizard what would be the correct syntax to define this variable on the editor?

thanks,
Giovanni

Hi Giovanni,

Thanks for your post.

The math needed for this cannot be down with the Strategy Wizard, so this must be hand coded in the code editor.

You mention "I would like to buy when the current price (c) crosses over c+bx*variable0"

If c is the close price, it would seem unlikely that the close price could cross over a higher number if this is calculated and re-saved on each bar.

Are you wanting to save the value of c+bx*variable0 on the first bar (or another previous bar) to be compared with later?

OK I made some confusion:It is probably easier to start from scratch and explain exactly the strategy I am trying to code:

BRange= the price range over the last n bars=the highest high of the last n bars (including the current bar) minus the lowest low of the last n bars (including the current bar)
n= number of lookback bars
bx= percentage multiplier of the BRange
c=current price
buyCh= c+ bx* Brange
enter long position if next bar higher than buyCh

Hello balucang,

It sounds like you want something like the following:

int n = 10;
double brange = 0;
double bx = 1.5;
double buych = 0;
protected override void OnBarUpdate()
{
if (Close[0] > buych)
EnterLong();

brange = MAX(Close, n)[0] - MIN(Close, n)[0];
buych = Close[0]+bx*brange;
}

ok tks for your help
