The trading strategy being analyzed is the first strategy in the thread: https://www.quantopian.com/posts/fundamentals-up-the-wazoo.
I found some redeeming qualities in the program, see the post: https://www.quantopian.com/posts/fundamentals-up-the-wazoo#5b61f8944ff1537cc224745f
Since there was an invitation to post a tearsheet for analysis in: https://www.quantopian.com/posts/tearsheet-feedback-thread, I did.
I posted a few tearsheets in succession where the action taken to increase performance was planned and deliberate as demonstrated by the tearsheets presented.
At each level raising the bar. Either by increasing the number of trades, the average net profit per trade or both at the same time. Each level with a “predetermined” intent and not necessarily a “forecast” to produce more, profitwise. None of the program's trading logic or stock selection methods were altered, only numeric variables. These new modifications to the strategy are in the same vein.
I could not just walk away after the last sentence in my previous tearsheet, see: https://www.quantopian.com/posts/tearsheet-feedback-thread#5b6853dcf73cd7004a6aaf69
If I did, it would have been an unsubstantiated claim. And, I do not like those. So, I felt obligated to change a few numbers again and raise the bar again to increase the output of the strategy's payoff matrix.
From the start of these modifications, I stated that the strategy had some hidden potential. It was not to discover this potential but to uncover it, and liberate it of its restrictive chains.
I look at a trading strategy's payoff matrix as a whole, a big block of data that you have to coerce to do what you want. You know you have no control over the price matrix P whatever its size, and this, that it be past or future price data. However, you do have control over the inventory matrix H, the how you trade.
A trade, in particular, does not interest me. But, a trade in general does. If you design automated trading strategies, almost by definition, they might trade a lot. And having thousands of trades will force you to look at the problem using averages.
Was it evident that you could do more? Well, the attached tearsheet does answer with a yes.
