I asked the question about what was meant by randomly generated charts from Jason101, because to me that usually means some sort of Random Walk, a Brownian motion or something normally distributed. And there is NO method that can have an edge if you're trading a Brownian Motion for example, so the comment made no sense to me, but perhaps he means something else. You could generate charts with certain statistical properties that enable a possible edge, but that would only have something to do with real trading if your model did behave reasonably like a market. And that's an incredibly difficult task (I've tried and am still trying).
I am not surprised about the difficulty in you finding a significant enough entry with random exit (more on this below) as I mentioned it to you on another thread. I think exits are more important and I can think of a few possible reasons, but I'll give an intuitive one. You decide to enter at a point based on some of the information (price or otherwise) up until that point. Once you're in, every minute that price is moving, you're picking up more and more new info that needs to be assessed. And surely one minute of this new info is MORE important than one minute of the history before entry because it directly affects your account, and because people are reacting based on this new info. Therefore as time goes on, the weight of the new information must at some point overwhelm in importance the conditions that got you into the trade in the first place. Sometimes this can happen quite quickly.
In terms of random entry. For me, entry and exit need to go hand in hand. They work together or they work against eachother. A particular entry can (and perhaps should) have a very different way of trade management until exit, from another type of entry. Others probably disagree. I wonder if your type of exit, may work well with random entry, but equally it might not work so well if you entered at a Fibonacci point or at a daily pivot or overnight in a set direction for example (please correct me if you believe it works equally well at all points and all times). However, I find it hard to believe that there is no entry that could enhance the profitability of your trades beyond what you get from random entry. Attempting to find an entry, which was significant enough such that a random exit would give enough profit, does not seem like the correct way to approach that problem. You'd be looking at the wrong thing.
I'm not suggesting I'm correct on all of this above, it's just my view.
