Write to file on trade event

I want to write data to a text file whose location I can specify, on each trade event. The program should write to a file both for when a trade opens, but also for when a trade closes. It should NOT be needed that more than one chart is open because the trade vent might be coming from a signal provider, who might be opening positions on many charts. More detailed information is in my requirements txt below.

Only someone who can implement exactly as in the requirements and quite fast should apply.
