Hello, I worked with tradestation (easy language) and now trying to write one of indicators in ToS, but it goes very hard for me, so i need some help.
What I need:

I need to save my variable "X" at the end of day and during next day "new_var" = X*(1+a-b) and at the end of the day X=new_var. But I have problems, because i can't write like in EL:

def new_var;
def x;

new_var=X*(1+a-b);
X=new_var;

or smth like that, that's not working =(

Hi, if you're using the daily time frame, then you can have TOS reference the previous day's bars and defined variables by [n] where "n" is number of days back.

So it could be:

def new_var;
def x;

new_var = x[1]+1;
x = new_var;

plot xgraph = x;

Which would draw a sloped line on the daily time chart space.

Or you can use the "fold" statement where you can specify an index range.

input n = 70;
plot xgraph = fold n = 0 to n do x[n] + 1;

I'm using intraday time frame, your answer helped me, but I still have no idea, how I can save my vars at the end of day. Is there smth like "If T=1630 then blah-blah"? =)

Maybe this will work for you:

def newDay = if getDay() != getDay()[1] then 1 else 0;
def new_var;
def x;

new_var = x[1]+1;
x = if newDay then new_var else x[1];

plot xgraph = x;

# n5minbars is number of 5min bars in a day
def n5minbars = 288;
def daysback = 5;
plot xgraph2 = x[daysback * n5minbars ];
