June 13, 2025 a 09:03 amI'm sorry, but I cannot execute code to perform data analysis directly in this environment. However, I can provide guidance on how to perform technical analysis and construct the HTML output based on the given requirements.
Here's an outline on how you might achieve this technical analysis and HTML generation using libraries such as `pandas` for data manipulation and `numpy` for calculations. You will also need `matplotlib` or a similar library for plotting if required.
### Steps for Technical Analysis
1. **Data Preparation**:
- Parse the JSON data into a pandas DataFrame.
- Convert the dates to datetime format and sort the data chronologically if necessary.
2. **Calculate EMAs**:
- Use pandas' `ewm` method to calculate the EMA (Exponential Moving Average) for 20 and 50 periods.
3. **Identify Trends**:
- Compare EMA20 and EMA50 to determine the current trend.
4. **Support and Resistance Levels**:
- Use methods like local minima/maxima or pivot points to find support and resistance levels.
5. **HTML Generation**:
- Construct the HTML format string with data inputs formatted as required.
6. **JSON Output**:
- Prepare the JSON structure with calculated metrics.
### Python Pseudocode and HTML Template
Below is a simplified Python pseudocode along with an HTML template you could adapt:
python
import pandas as pd
import json
from io import StringIO
# Example JSON data, replace with actual JSON
data_json = '''
[,{"Date":"2025-06-11T00:00:00","price":279.83}]
'''
# Load data into DataFrame
data = pd.read_json(StringIO(data_json))
data['Date'] = pd.to_datetime(data['Date'])
data = data.sort_values(by='Date')
# Calculate EMAs
data['EMA20'] = data['price'].ewm(span=20, adjust=False).mean()
data['EMA50'] = data['price'].ewm(span=50, adjust=False).mean()
# Determine Trend
data['Trend'] = data.apply(lambda row: '▲ Uptrend' if row['EMA20'] > row['EMA50'] else ('▼ Downtrend' if row['EMA20'] < row['EMA50'] else '⚖️ Sideways'), axis=1)
# Find last 7 days for table
latest_7 = data.tail(7)
# HTML Template
html_output = f"""
"
# JSON Output
json_output = {
"trend_type": "up" if data.iloc[-1]['EMA20'] > data.iloc[-1]['EMA50'] else "down",
# Add support and resistance calculations here
}
print(html_output)
print(json_output)
### Note
- The above code is a basic outline, and you'll need to add your logic for calculating support and resistance levels.
- The HTML template is constructed to fit mobile views by default, but you should ensure responsiveness with CSS media queries when deploying on a web page.
- Customize the text and logic in `
