8 days, 47 trades & +11.17R after my
MAE- assisted
light bulb moment, I thought I'd quickly share a few statistics and the possible implications these may have;
* 27 winners (35.91R), 20 losers (24.75R)
* The above means Avg winner= 1.33R, Avg loser= 1.2375R
* 57% (0.574468) win rate
* 0.2374466 expectancy.
First impressions are good. The only number that really matters to me is the expectancy...considering
Roulette gives the house a 5.26% edge (0.0526 expectancy), I'll definitely settle for the above!
However, the other values can cause problems of adherence to/tolerance of the edge. One potential problem that was obvious to me was the effect of any decent drawdown. If the system is making a little more on it's winners than it's losing on the losers, then, (assuming a random distribution of wins and losses) would it be more likely to chop it's way up the Y axis, opening up the possibility for a pretty severe drawdown relative to the slow but consistent collection of R's??
As it goes, that question got answered on Tuesday 13th September :)- 6 wins, 10 losses (!), 6.23R down. 62.7% of the prior 5 trading days gain...(9.93R)
If that day's excluded, we have the following stats;
* 21 wins (29.92R), 10 losers (12.53R)
* Avg Win= 1.4248R, Avg loss= 1.253R
* 68% (0.6774193)win rate
* 0.5609936 Expectancy.
There's two main choices that I see: choose to ride out those ugly days
or try to limit them. I've noticed that the other days huddle quite nicely around that 0.56R expectancy while that Tuesday is sitting all on it's own at the edge of the bell curve (-0.389R)
So I'm thinking, what if I
apply the same concept of MAE to the WHOLE trading day, effectively treating it as a "trade"? Maybe below -XR my odds of making money are reduced enough to warrant cutting the "DayTrade" loose?
I'll continue to trade/collect data and see what picture it paints me...
