I am not sure how to reconcile the difference the long term and short term results of my trading strategies.
I was working on a strategy for trading the ES. Not to make millions while I am sleeping, but rather to test whether what I am planning makes any sense. The strategy enters a (1) contract when certain conditions occur and exits when other conditions occur. It had no stops or targets. I back tested it for 90 days and had what I think are very good results. This is only tested for long trades. 10 minute chart. I have not set the strategy for shorts yet

--------------------------------------
So then I decided to test it on a longer time period. 3000 days. The results were horrible. It lost tons of money.
Does this mean.
1. Short term results are statistically irrelevant?
2. No strategy will be correct in all market conditions (we are in a bit of a bull run)?
3. I am mis-evaluating the strategy by only looking the fact that it made money.
I guess I am just really not sure what I my next steps should be. And part of me questions whether long term evaluation is really correct since it covers so many various market conditions. I am not sure how I would fix it.
Although this particular strategy is for the ES, I think it is a universal question. Should I care about those long term results?
Thanks for any insights.
