There are two main reasons why your OP is dismissed as dreaming. The first is that there are simply hundreds (thousands ?) of people out there who claim to have a foolproof way of picking the market. Several have been through here. Despite having this foolproof method, they would rather spend their time advising other people and shooting the breeze instead of making stupendous amounts of money. Personally if I had a way to pick the market I would STFU about it (so that no-one else finds out) and get on with making money.
The second reason is that despite having this surefire way of making money (that the market as a whole isn't using), you can't manage to find the funds to actually put it into practice in the real world and you're only able to do it with play money. Whilst this may be completely true, I would move mountains to raise the necessary funds to put my idea into practice in a similar situation.
By saying that you must be a barefaced liar or the best technician in history, you're excluding a lot of middle ground. You could be just having a run of good luck - I was briefly able to pick winning horses, then my luck ran out, fortunately I too was only playing with virtual money after the first day (the first day I turned a tidy £150 profit

). Alternatively you could be retrospectively including/excluding certain trades on the basis that you really meant to make/not make that trade.
It is entirely possible that you are the best technician in history but it's more likely IMO that one or more of the other factors are in play.
Great, let us know when you buy/sell and the fees and taxes involved.
