Requests for additional features

Thank you for the excellent tool. I used Google Translate to translate this from Japanese to English, so I apologize if there are any grammatical or vocabulary errors.

I would like to express my hopes for the future.

I would like to request the introduction of second-by-second charts for scalping practice.

I would especially like 15-second and 5-second charts.

Since these are already available as custom indicators in MT4 and MT5, and implemented in TradingView, I would appreciate your positive consideration in order to allow for backtesting and trading practice in a more realistic setting.
