Hi Zheka, English is not my mother language and sometime I can not get the subtle meanings of some post. Trust me or not, but it is as it is.
I agree with you: "SR rule" is quite a rough one. This is why I do not invest too much time in evaluating several subtle situations. My idea is that I should stop a trade system way before a margin call thanks to tools like CBI or Equity trading. I use the SR rule only to be sure I am not reinvesting too much. If I stop a system and restart it after 2 months I consider it as a brand new one. Right or wrong is how I use the SR rule. But you can cut the reinvest profit by 10 (just an example) if you think that the standard rule is too much or do not reinvest at all and accumulate your profits...
