ya it's not DB its little modified as it kept the mid dip above the zero line... it can be constructed more effectively after some fine tuning as i said in the first post...
your pic is of short straddle? what are legs and it values that have been used?
no question of option repair in static strategies
BTW when you say back testing framework does it have option data for last five years with all the strike prices? can you explain in length so that we know where we are heading.
thanks

For back testing:
Only index data is required for final payoff while the cost of spread can be calculated based on current data (the cost of spread will more or less will always be same).
For non-static strategies, I use the VIX data (available from Mar'09). VIX is a close approximation of IVs and with some tweaking you can use it in place of IV.
Let me know what strategies would you like to be back tested.
