In my backtesting i aimed for an average 3:1 profit/drawdown ratio (MAR ratio of 3), ie. if i want to make 60% a year i should sometimes expect 20% drawdowns, if i want to make 100% a year then 33% drawdowns etc.
I think that is doable for an automated day trading strategy. I know long term trend following strategies cannot achieve this kind of MAR ratio. If you look at trend following hedge funds, they have MAR ratios less than 1. Although they are much more size scalable than my day trading could ever be.
Regarding months of drawdown, this is something i did not try to optimize at all, if market conditions do not suit the system for X months, then there is little i can do to force the system out of any long drawdown. Only a change in market conditions can do that. In general quiet market conditions are bad for the system although this is not always true.
I don't have patience, actually I do, but my back testing shows winners let me in and take off whether one minute, 60 minute, daily, weekly and monthly trades. So I have number of bars duration rules, if not at breakeven plus fees plus lunch(man's got to eat) in so many rules, new target to get out. This cuts out of half my bad or not taking off as it should. I hedge now any trade over 59 minutes, this substantially altered drawdowns, plus I have been charting nearly four decades and gotten good at reading charts, so when I feel a reversion to the mean is due, and if I don't wish to get out, perhaps dividends are due, I will hedge open profits.
So overall, drawdowns are much erased, can make something to hedge open profits, added size and instruments, plus I can dance many more options plays in range bound markets.
I have zero faith in R:R, what is expected either comes and make me look like a fool for getting out too early or never reaches that goal that often too far away. I can see existing partial at long term trend line but to have certain number to exist longer term trading cause it reached "3" .
Many Hedge funds, most can't even make S&P500 Index. I now have all automated, from scalping to very long term, scalping has lowest losing percentages, in/out in few minutes, day trading, so many minutes have to be at BE plus one tick, I rent a seat, so one tick is huge for me times volume, so even if I have sixteen trades of one tick, bring them on. But all systems are heavy into time values, can't se be sitting there in the hole for months. Much easier on subconscious. So instead of trading and forcing myself from falling asleep just waiting, kick back and let laptops take the trades and I just study so much more on risk management.
Do you use weekly and monthly charts for longer term?
Good luck to you.
