Syntax Help on Schedule Function

Hey, I am having trouble with my code, I simply don't understand what I am doing wrong with the syntax.
here is the code

def initialize(context):  
    context.stock =sid(39940)  
    schedule_function(  
    myfunc,  
    date_rules.every_day(),)  

    schedule_function(  
    myotherfunc,  
    date_rules.every_day(),  
    time_rules.market_close(minutes=2))  
total_minutes = 6*60 + 30

for i in range(total_minutes):  
    # Every 30 minutes run schedule  
        if i % 30 == 0:  
            schedule_function(  
            myfunc  
            date_rule = date_rules.every_day(),  
            time_rule=time_rules.market_open(minutes=i),)  
total_minutes = 6*60 + 30

for i in range(total_minutes):  
    # Every 30 minutes run schedule  
        if i % 30 == 0:  
            schedule_function(  
            handle_data  
            date_rule=date_rules.every_day(),  
            time_rule=time_rules.market_open(minutes=i),)

def myfunc_(context, data):  
    open_price= data[context.stock].open_price  
    order(context.stock, 100, style=StopOrder(open_price))

def handle_data(context, data):  
    data[context.stock].open_price  
    curr_bar = data[context.stock].price  
    open_price= data[context.stock].open_price  
    if curr_bar > open_price :  

        order(context.stock, 100, style=StopOrder(open_price))  
def myfunc(context, data):  
    data[context.stock].open_price  
    curr_bar = data[context.stock].price  
    open_price= data[context.stock].open_price  

    if curr_bar <= open_price :


        order(context.stock, -100, style=LimitOrder(open_price))  

def myotherfunc(context,data):  
    order(context.stock, -100)

don't use "," after the last argument in a function, for instance "date_rules.every_day(),)" will certainly throw an error

This is not correct. It is perfectly legal in Python to have a comma after the last item in any list:

>>> def foo(*args, **kwargs):  
...     print args  
...     print kwargs  
...  
>>> foo('a', 'b',)  
('a', 'b')  
{}  
>>> foo('a', 'b', c='d',)  
('a', 'b')  
{'c': 'd'}  
>>>

Getting back to the original question, whitespace and indentation are syntactically significant in Python, and in your initialize() function, everything after the first "total_minutes = 6*60 + 30" is indented four spaces less than it should be. If you accurately replicated your indentation in the sample code above, then that's your problem, or at least a problem. If you didn't accurately replicate your indentation, then you need to accurately replicate your indentation in the code sample you ask us to look at for us to be able to effectively help you find syntax issues. ;-)
