Quote from OneFive:
Thanks, Maverick, for the insight and advice. I have been working through developing my own modifications. Of course, this leads to the need for an interpretation of the numbers I am generating since what will be meaningful in my system may not be very similar to the Fisher system or any other. Since this is a product of experience but also data collection, do you have any thoughts on how much data to accumulate in order to derive useful parameters? While I could potentially backtest this, my sense is that I need to accumulate this data and experience over real time to develop the understanding of what is happening and how to interpret the results. Your own experience in modifying the number line parameters could prove pretty helpful, not in terms of what to use, but how long it took you before you got to a point of comfort and confidence that your methods were solid. Are there any pitfalls to be especially aware of in trying to build a personal model?
Thanks again.
Do NOT backtest. Form a hypothesis first based on whatever experience or knowledge you have (as little as it may me), then collect data and see if the data is agreeing with your hypothesis. Not the other way around. One you have some sound ideas, the important thing to remember is to be absolutely consistent in how you analyze and compare your data. Remember, form the idea first, then collect the data. Don't just grab a lot of data and say, oh, it looks like every time there is an A Up on monday, there is follow through the rest of the week. You'll be chasing a lot of rabbits.
Try to form a scoring system that is consistent. Maybe all currencies get scored one way and equities another. But don't take ideas that work in equities and just arbitrarily apply them to currencies. Make sure when comparing relative strength or weakness that you are doing it in the same time frames with the same OR so you can measure data specifically from that time period. This can get tricky with commodities vs commodity ETF's for example. And even more so with currencies. Since currencies have three different main time zones.
It's going to take a lot of time. I doubt most people will ever put the effort into it which means there is a lot of edge out there for you if you are willing to make that time sacrifice. I promise you this, if you put the time into the number line analysis, you will get information that absolutely no one out there is getting from price charts. But there are no shortcuts unfortunately. Just be consistent, match up the time frames and OR consistently, form your ideas first, collect the data and try to be objective as you can about the results.
One thing I try to do is keep everything ACD based. I don't mix and match with other technical stuff. So I'm always asking myself the question, does this make sense with the core ACD logic? Is this what should be happening? If the data is giving me something inconclusive, I do NOT try to manipulate the data to agree with me. I come up with new ideas. There is an old saying in statistics, if you torture data enough, you can make it say anything.
If you tell me what products you are specifically looking at I can try to give you some more pointers specifically geared towards those products.
