Thanks. It is hard to retire. REMEMBER, in trading there is always something to do when it doesn't work. You have to discover that something.
Equity curve stops and some form of position size signal fixes this. His method is legit, even if it may require market orderz to get in and out of real positions. The market may look like a scientific problem, but in the end, all quants find out what you did: It works until it doesn't. Risk management is the fundamental sacred skill of all life on Earth. Everything works until it doesn't.
The market is anything but a scientific problem, or math problem, nor can the magical solution process be found in any trading course or book.

That would be rather devastating to your overall performance. Trade wisdom and process count
