Quote from random trader:
Even though English is my second language, I would argue "missed trades cost you more than bad trades" means "all your missed trade as a whole cost more than all your bad trades as a whole", not "each missed trade costs you more than each bad trade". Correct me if I am wrong.
During the discussions, I assumed we all had probability considered and included in the calculation because I have brought it up so many times on this thread. Did not think there was a need to point it out explicitly every time. I was wrong.
In your case, a "good trade" makes you $250. So if we assume that every "missed" trade would have been a good trade, you would have to have 4 "missed" trades, all of which would have been good trades, to equal just one bad trade.
The problem is why are we assuming that a "missed" trade is always a good trade?
Tell you what: in my 30+ years of trading, I have mostly used limit orders enter positions. So I've "missed" many trades at the time. Some of those would have been "good" trades. But there are some trades that I "missed", that I then cancelled the trade, and later had an opportunity to make the trade at an even better price than I had intended. Sometimes I haven't wanted to make the trade by that time, having had an opportunity to reconsider.
Since you're a statistical expert, I would assume that you don't make these types of statements lightly, that you must have some study that covers your missed trades versus bad trades. So why not just trot out the study that shows all of the missed trades versus all the bad trades?
But most people I know talk about the one that "got away". They don't talk about the time it worked in their favor. Either way, any evidence that your statement is true would be strictly annecdotal since it's nearly impossible to study the trades that you "missed".
What I would imagine is being talked about in Market Wizards is a guy who strictly limits his losses, and lets his profits run, and therefore, if he "misses" a trade, and then sits there like a wooden indian, refusing to make another trade later on because he could not make it at the original level, and simply watches as this trade becomes the winner of all time, that this trade then would outweigh all of those little losses he took.
The difference is, your strategy limits your gains, to 1/4 of your losses, so again, you need to miss 4X as many trades as all of your losers to make this claim. I find that to be unlikely.
