Hi,
I am looing for some bet platform where winning probability is 50/50 (or more ), has DEMO account, and small stakes as low as $1.
O, and they shouldn't escape with my money
what?! If you treat trading like going to the casino this is what you will get back in return.
Why bother playing a 50-50 game anyway, you are not going to win anything and not going to lose... so no point?
trade following the moving average if you have to
You didn't say you were binary betting! I thought you meant trading.
And yes, in a fixed odds 50-50 (as you might find in a casino) you will not win or lose overall. It is not possible to maintain any win. If you have a trading strategy that has an 'edge' over the market however this obviously works in your favour.
And no there is nothing wrong with a basic moving average. I wouldn't recommend it as a sole strategy but it is better than random guessing. As for it working 100 years ago but not today that is rubbish... look at the huge market crash that has happened, following the MA would have gotten you into that nicely. Also, prior to that, the daily MA was rising steadily along with price. Combine it with proper money management and you'd be surprised what is possible!
