    With no tax game, such as war, most game is 50:50. However, with tax (commission) such as security trading and blackjack, successful trader might be ONLY 10% or less in the long run. Most zero-sum game may be around 50:50. Many research paper support it, such as...

    10% success rate is better than 60% success rate?

    I agree that it will be VERY difficult to make a strategy, 1) with 10% success rate and 2) with 90% rate. It is probably because success rate in most game will be between 40% and 60%. For example, Baccarat has 48% success rate, if I heard correctly. How about lotto? Many different style of...

    Probably, your cash of 30K will be used to BUY of 60K (cash30K + loan 30K) The ratio of 50:50 varies time-to-time, by FederalReserve, not by each broker. Back in 1920s before Great Depression, the ratio was 10:90 which was reason for the Great bubble. There is some youtube clip, to show a...

    If I heard correctly, most ETF and fund already paid appropriate stamp while fund manager in the company buy/sell. For example, suppose you borrow my cash and run the cash for a year of trading to return back to me, then there is NO tax on money transfer between you and me, after one year...

    Many (most?) countries does not charge tax to ETF. I think it is since the company running ETF already paid corporate tax and etc. So UK ETF is not the only ETF with no stamp duty.

    0.5% in UK might be the highest so far. (China 0.1% and HK and Korea 0.3% if I heard correctly) For example, if you trade any UK equity (no matter where you lives and no matter which broker you use), say roughly everyday buy/sell with initial seed. then it takes less than a year to accumulate...

    Good to here. Probably >90% of ETers are in US based, in my estimate. That is why I regarded you as US tax payer. Sorry for misunderstanding. PS) Could you show me link to explain annual income tax bracket in UK?

    Good point. However, APIs are all different in every brokers so that we should study every individual API whenever we change broker. However, web is pretty much standard all over the world and it will last next 100 years. Therefore it is easy to change broker, without addicting ONE BROKER long...
