For modern computing/finance type of people (I was but now have reformed) the lack of financial data is a problem. Even if you can get access to every trade, which is hard, the amount of data is not what modern machine learning types require.
Thr EMH is a hard mistress too. There is no amount of data that can help you solve unsolvable equations.
So alot fall into this trap, synthetic data. Some of the best statisticians on the planet have. It is so tempting to believe that there is money to be made by being cleaver trader I markets.
General, there is not. Buy and hold is not a shibolith it is a strategy. It is the only strategy that can be replicated.
Synthesizing data to disprove buy and hold is wishful thinking. Data snooping.
