Hello Cubt
When we take back testing results we forget to check if we would get a fill at the price the back tests are showing . . .
Besides the trading Cost, Slippage is a big concern but that is know and acknowledged by everyone.
I have seen many people back testing do not even consider Forwardization charges/costs?
2008 to 2013, 5 years => 60 months => that will cost you 1500 to 1800 points to shift your futures position from one expiry to next
2100 trades should cost you 6300 points (1.5 points per trade entry & exit) in brokerage & taxes
minimum slippage can be consider at 4200 points ( avg slippage 1 point per trade i.e. entry & exit)
Without all these how does one arrive at a realistic estimation?
Cheers
Happy

I have worked out a full cost ratio which is approx 0.1176% of trade cost in cash market Intraday. Delivery traders are 5 times Intraday.
NFO and Options are lot more complicated but when you shrink all numbers down, it comes at 0.09% and improves in your favour with lot size growth.
Both are approximations but idea is to budget for this costs; set aside few extra points (but not too much) so that if ur AFL says X% profit, you will get at least X%.
Also, I play around with entry prices. Besides enter at candle close or enter-at-next-open or permutation off O H L C such as (2 * H + L) / 3 for long positions and (H + 2 L)/ 3 will be more likely to get realistic in trade prices.
Fortunately, given the way I have structured my ATS, my slippages are low
and less than 0.5%.
