Using the script function

[maverickmitch]

Hi I am new to programming. I have a long script that gives me a buy or sell signal and I don't know how to use the script function and apply it to mutliple timeframes within one chart.

How would I program thinkscript to run a given script on various timeframes and put a label for each timeframe at the top? (i.e. SMA10 being greater than SMA50 on a 5m, 10, 1hr, 1d label at the top) using the script function in the thinkscript.

This uses the script named sma to define the relationship between the 2 simple moving averages in a plot named cond. The script allows you to somewhat shorten the coding of the labels at the various timeframes you noted.

script sma {
    input agg = AggregationPeriod.FIVE_MIN;
    plot cond  = SimpleMovingAvg(close(period = agg), 10) > SimpleMovingAvg(close(period = agg), 50);
}

AddLabel(1, 5 , if sma().cond == 1 then Color.GREEN else Color.RED);
AddLabel(1, 10, if sma(AggregationPeriod.TEN_MIN).cond == 1 then Color.GREEN else Color.RED);
AddLabel(1, 60, if sma(AggregationPeriod.HOUR).cond == 1 then Color.GREEN else Color.RED);
AddLabel(1, "DAY", if sma(AggregationPeriod.DAY).cond == 1 then Color.GREEN else Color.RED);

I am trying to use the script function with an indicator I written. I am trying to shorten the code but have found little in the Thinkscript discussion that adequately describes what goes inside the {}. Is there a complete discussion someplace?

usual things within a script { }
1 or more inputs,
some formulas,
1 or more plots,


think of the script function, as creating your own custum function/study.
when you use a built in study, like
MovAvgExponential, there are 4 input parameters that can be entered.
price
length
displace
show breakout signals

to use it , you could supply all 4 parameters,
def k = MovAvgExponential( close, 22, 0, yes);
then it calculates a number and assigns to k.

there are 3 outputs, plots, from this study. the default output value is the first plot.


an example script,

script stuff {
input a = 0;
input z = 0;
def b = a*5+z;
plot c = b+3;
plot d = b/3;
}

to use a script, use its name, and some parameters,

def g = stuff( 4, 5 );
the parameter(s) used within ( ) , will each be assigned to an input variable, in the script.
input a , will become equal to 4
input z , will become equal to 5

g will be equal to the first plot, c.
this could also be written as,
def g = stuff( 4, 5).c;


not all parameters need to be used, but you have to start with the left ( first). if you want to use the 2nd.


plot is used to send a number out of the script. the first plot is the default output.

to read the 2nd output plot, add d to the end.
def u = stuff( 4,5 ).d;

although plot is used to generate output, a script only produces a number. it can't draw anything.

Thanks for the clarifying response Halcyonguy. Simply put, I now see that what goes inside the {} is another script.
