Python snippet for reference (EMA-based signal logic, can inspire NinjaScript implementation):

import yfinance as yf
import pandas as pd

data = yf.download('ES=F', period='3mo', interval='15m')
data['EMA_short'] = data['Close'].ewm(span=10).mean()
data['EMA_long'] = data['Close'].ewm(span=50).mean()
data['Signal'] = 0
data.loc[data['EMA_short'] > data['EMA_long'], 'Signal'] = 1
data.loc[data['EMA_short'] < data['EMA_long'], 'Signal'] = -1
