Creating a KPI EA

I would like to show my MT5 account and stats on my website. That means I need an EA which creates the stats once a day (probably with OnTimer). These stats shoukd get calculated:

- Account history in %

- Max. Drawdown since start

- Max. Return since start

- CAGR

- Risk of Ruin (Loss size, Probability of loss, Consecutive loosing trades)

- Value at Risk

- Sharpe Ratio

- Sortino Ratio

- Calmar Ratio

- Profit Factor

- Winrate

- Trades since start

- Monthly development in %

- Trade history

The EA should create a json file which gets sent to my web-host / database automatically.
