How To Handle Losing Streaks
- A proposed betting approach -
Perhaps the prime objective for a player
serious about reaching professional status should be - finding out how
to best handle losing streaks. Any valid long-term money management
method must take this extremely important factor into account.
The "Kelly" method (discussed in
previous letters) is optimal for increasing the bankroll during a positive
series of wagers where winners are numerous enough to have produced a flat bet
profit; however, the same method can decimate a bankroll's hard-won
profits during even short losing streaks.
The most used of all betting approaches is
likely the "Fixed Percentage" approach. This is where a fixed
% of bankroll (example - 5%) is always used to figure the next bet
amount. This approach (which essentially becomes "flat
betting" when a comfort level ceiling has been reached) somewhat smoothes the more radical bankroll
gyrations of the Kelly approach, but it still cuts deeply into bankroll
profits during losing streaks.
I believe it was James Quinn who, about 20
years back, wrote about a method he called, "Fixed Percentage -
Minimum." This is one of the better money management methods for
lessening the often devastating effects of grouped clusters of losses - the
dreaded, yet inevitable, losing streak.
A warning: The F%M method performs very
poorly when you are in an alternating pattern. A pattern like this:
w,l,w,l,w,w,l,l,w,l,l,w. Because most players don't come close to hitting
45-50 % of their win bets, for this pattern to last over an extended series
of wagers is rare. The usual patterns for most players most of the
time settle into clusters of (smaller) groups of wins and (larger) groups of
losses.
Why the F%M method performs poorly in the
alternating pattern runs will become apparent. Here are the
"rules" -
You will bet a fixed percentage
of your starting bankroll after every win - but you will bet only a
non-changing base amount after every loss.
Let's say you set your fixed
percentage at 5% - that also becomes the non-changing base bet at that
time. If your starting bankroll is $1000, your starting bet and
your un-changing base bet is then $50.
So you can get a better idea of
this approach, below is an example of the method applied to a series of 15
races. Red numbers are the races where the base bet minimum was
used after a loss:
