I just happened to reread the blind mouse thread this weekend so I was looking at that plus some of your other ideas for trying to catch the yearly extreme.
I have found better ways since then, a multipronged approach that targets smaller waypoints.
Using the current 21.153% waypoints:
Always look to double a $minimum size entry (anything doubled can be halved).
If $min & no double, liquidate in profit.
$min times 2, 4, or 8 for up to 55 pips: liquidate at any price <55 pips, if 55 (+4, 8, or 16%) then reduce size by 50% & see what more
I can get. Any pips above 55 may be used to add another pair.
Revert to $min for hundreds of pips (+21.153%) if I hold a stop from a monthly extreme or breakout
(a small price to pay for the possibility of an effortless waypoint).
I make no claim that this is the best way, it is just my way.
