The problem is not so much that this process can work or not, it is in developing useful questions able to give unambiguous signals. I personally have experienced a signal from my subconscious when i was engaged in market activities that detected two black swan events. In eother case i went on the defensive in the preceding week(s) to protect myself. Those two events were the 1987 market crash and 9/11 itself. Other less ambiguous signals were also experienced over the years.
To exploit something like this, it is necessary to understand the target market and to establish preset orders to take clear advantage of the information. Then you must completely disengage from the market itself and most certainly avoid reselling yourself during the selling window. This is very difficult. A large problem is that actual precision is often lacking as to timing and price points will follow a natural pattern as well.
Thus what is so far reported looks more like luck although 35 tests in the earlier study is promising. Otherwise, have fun creating effective experiments, and do not mistake a high wind as a normal condition for the flight worthiness of a turkey.
Regarding the financial results, on an initial investment of $10,000 we gained approximately $16,000 with a total of $26,000 at the end of trial 5. The first five trials were conducted on days of large market swings, therefore the potential gains were very large. Trials 6 and 7 happened on days of small market changes and, despite resulting in correct predictions, produced small losses because of the mechanics of the options trading vehicle. A timing issue in the trade of trial 7 resulted in an additional monetary loss of approximately $12,000. However, it is important to stress that this was in spite of the prediction itself being correct. (Without this timing error, total cash at the end of the project would have amounted to $38,000, or a return of almost 400% on the investment in a span of about two weeks.)
