Hi,
There is an issue when passing python datetime objects to copy_rates_range(symbol, timeframe, date_from, date_to)
Here is a part of the stack trace:
--- Logging error ---

TypeError: Object of type datetime is not JSON serializable
Call stack:

return _run_code(code, main_globals, None,

exec(code, run_globals)
I was able to solve this by passing timestamps instead of datetime objects, The docs says that either timestamp or datetime is acceptable. Have to mention that copy_rates_from() is fine with datetime.
