New to algo trading and Quantopian, need help with placing orders

Hello, as I stated above, I'm very new to all of this and I'm trying to learn the basics. I was watching a youtube tutorial from a guy and I decided to just copy his algorithm and try to backtest it my self, just to start getting used to the platform. I copied his code word by word and somehow when I run it it doesn't place any orders. This video is about 3 years old so maybe something changed and that is why it doesn't work?
I appreciate the help, thanks.

This is the code:

def initialize(context):  
    context.aapl = sid(24)  
def hande_data(context, data):  
    hist = data.history(context.aapl, 'price', 50, '1d')  
    log.info(hist.head())  
    sma_50 = hist.mean()  
    sma_20 = hist[-20:].mean()  
    open_orders = get_open_orders()  
    if sma_20 > sma_50:  
        if context.aapl not in open_orders:  
            order_target_percent(context.aapl, 1.0)  
    elif sma_50 > sma_20:  
        if context.aapl not in open_orders:  
            order_target_percent(context.aapl, -1.0)  
    record(leverage = context.account.leverage)

Simple typo. handle_data is spelled wrong (forgot the 'l'). Change that and it will work.

Good luck.
