MyPnL.pro's answer
MyPnL is designed for retail traders, including forex, options, futures, and intraday traders, who want to analyze their performance, improve discipline, and develop consistent trading habits. It is especially useful for traders who prefer visual trade review and structured performance insights.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
MyPnL.pro's answer
MyPnL was created to solve the common problem of inconsistent and time-consuming trade journaling. Many traders already review their trades using screenshots, but lacked a structured way to analyze them. MyPnL was built to bridge this gap by combining visual trade records with meaningful performance analytics.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
