Making Discretionary Tweaks to Systematic Strategies
My trading of this strategy so far has been mostly rigid in terms of sticking to the model’s trading calls and the stop levels used. The two changes I have made (changing HE & LE entry to 8:35AM and using the -3.0 stop loss on KC) were confirmed by math over two years (net impact to expected P & L performance). But I would like to think that as one gains experience, knowledge and expertise, it will be feasible to make slight discretionary adjustments to improve the odds of success, while still keeping the same core trade premise. That being said, here are a few discretionary “tweaks” that could be made as I get more experience interpreting the markets I’m trading.
Adjusting Stop Loss Levels to Match Existing Volatility
I track a series of stop loss levels with each instrument against the 4 main trading signal variants I have developed. They basically are:
· 1 contract, $1,000 stop loss
· 1 contract, $500 stop loss
· 2 contracts, $300 stop loss per contract with $600 total stop loss.
For NQ these different stop losses translate to:
· 1 contract, -50 points
· 1 contract, -25 points
· 2 contracts, -15 points each, -30 total points
I’m currently trading the 1 contract, -25 point stop approach as it has a slightly better positive expectancy over the past 2 years. But for different time periods over that 2 year stretch, the 1 contract, -50 point stop has traded better (higher volatility periods) and the 2 contract, -15 point stop each has traded better (low volatility periods). Recently the 2 contract, 15 point stop approach outperformed from Jan 2nd – 26th during the market melt up. Unsurprisingly as volatility bumped up this week, the 1 contract -50 point stop approach performed best as its wider stop traded the volatility better. I would think tweaking the stop approach to fit market conditions would be something that can translate into better profits.
Another example regarding CL. In 2015 using a 1 contract -$1000 stop loss was by far the best performer. In 2016, the 1 contract, $1,000 stop and a 2 contract $500 stop each contract performed about even. In 2017 to present, the 2 contract $500 stop each contract performed the best. My guess this is attributable to the declining volatility in CL over the past three years.
Swapping Instruments in the Basket
Secondly,
@southall replied to my consideration for changing the KC stop that I might consider changing products to trade due to KC increased slippage. I’ve back tested other “softs” and the grains with decent back tested returns in SB, CC, and ZW. Along with additional slippage in KC, it has been in an uninspiring trading range between 120.00 and 128.00 since October. So the question begs should I replace KC with something else trading with more volatility right now? Here again I think gaining experience with these products every day will enable me to pick and choose which instruments to trade in a given sector. Other softs and grains that have higher volatility than KC right now are performing better.
Anyone want to share their thoughts with making minor discretionary tweaks to their trading systems / strategies for taking single day trades or 1 – 3 day swing trades? How long did it take for you to be “in tune” with an individual market to make stop loss level tweaks or swap instruments you were trading to something else, but still trading your core premise / strategy?
