DislikedMost systems are just working temporarily. Finding out which systems work for decades is what I am researching on a constant basis. And for that, 600 trades on a 1-minute time-frame is far from enough. It won't show how this system performs over the long haul. You still need major economic shifts in your trading data, and that only comes from years or decades of data.
Otherwise you will never know if it is just a temporary inefficiency/luck or a real market inefficiency that has worked over the last years and is likely to continue working for years...Ignored
I agree that 600 for 1 minute time-frame seems too little unless those trades are selected to be representative over most market conditions, which would not be likely if they were in a single time period. In general the problem is the common issue of finding a representative sample. Many statistical techniques are available in other areas such as population sampling which might give some help in determining how big a sample is necessary. However, I am not sure they are all directly applicable as some of the underlying assumptions may not hold for markets. For example in sampling a population you normally know how big the total population is, but who knows how many distinct market condition can actually happen. My guess is that it is more about finding something that works in enough conditions to provide sufficient returns to more than cover the possible losses in extreme or unusual conditions.
) if its NOT consistent then its not worth it; Remember: the key its from the "potential entry point it WILL move up or down, forget "candles" think about a vertical move
