Although I dont have a memorisation strategy set in stone yet with respect to the option strategies, I think I would go about it this way:
1.There are strategies that i will commit to memory completely in terms of Value,Profit,Max P,Max L, Break points
For me these are Covered Call,Protective Put , Collar and Box Spread.
2.The rest of the option strategies in terms of Value,Profit,Max P, Max L,BPs can be sorta derived from the payoff/profit diagramms and/or certain rules , that to me , are easier to memorise than the actual formulas.
Value=trivial from definition
Profit=trivial (ValueCosts of options)
Max Profit=First look at payoff diagramm, if upside is infinite then stop, we found the answer.If upside is not infinite then max profit=coresponding strike prices + cost of options. (exception being butterfly spread)
Max Loss=Cost of options with reversed signs
Breakeven=specific combinations of strike prices and max Loss.
3.Example : Bull Spread (long call x1+short call x2)
 V=max(0,SX1)max(0,SX2)
 Profit=Vcosts=Vc1+c2

Max Profit=coresponding strike prices and costs. coresponding strikes can be read directly from equation 1,just look at sign before strike prices in first equation (X1) and (X2). This gives X2X1. Now combine with costs,we yield [X2X1c1+c2]
 Max Loss=costs with reversed signs=c1c2
 BreakEven=X1+max loss=X1+c1c2
…So perhaps i just need to remember 4 strategies completely, and the other 4 i could derive with two pieces of info:
 Definition of strategy
 Break even points in terms of Max Loss
Still need to test this out though
