Brother candle,Quote from candletrader:
This thread has already touched on Mark Weinstein's claim to have never had a losing week... as I previously stated, the Mark Weinstein interview kinda lacked credibility... even Schwager conceded that Weinstein's spiel sounded preposterous...
I thought I would bring up another stat, this time from the New Market Wizards book and in the Linda Bradford Raschke chapter...
The question and answer:
What percentage of your trades are profitable?
About 70 percent.
... evoked a further question from Schwager:
Is your average winner also larger than your average loser?
On my short-term trades, on a per contract basis, my average win is about $450, and my average loss is about $200.
So, if I am reading this right, Linda is hitting 2:1 with 70%... anyone dig this?
Take the average of the following numbers: 50, 45, 40, 20, -10. Take note of what it is. Now, the average of these numbers: 1000, 50, 45, 40, 20, -10. One number and the average is thrown off by several hundred percent. In other words, the average _BY_ITSELF_ is worthless measure.
Making statements about averages is nearly worthless in order to derive any conclusions without further statistics like standard deviation etc. In fact, I would not trust ANY statistical statement unless it was in a VERY clear form with all the proper measures and the methods that were used, etc.
A better measure in this case is a moving median, but all stats have some weakness. That is why usually stats are given with other meausres and the probability distributions they are assuming...
