加倍方法或玩赌场 (Doubling up method or playing casino)

Hi everyone,

I was thinking about one strategy which I called doubling up method but I want to share it and you to review and make comments.

OK let's explain what I am talking about.

When we play simple Rulet we can use doubling up method but I think it is prohibited by casinos. For example let us asume that we have 100 000$. Let's place 1000$ on red, we lost!, place another 2000$ on red, we lost, place another 4000$ on red, we lost!, again doubled sum 8000$ on red, we lost and so on. as attempts rises the chance that this red will be done increases. So in this case, if we place 8000$ and we will win 8000$ which is more than lost sum of 1000+2000+4000 = 7000. If there is two attempts the chances are 50/50, but if there are 10 attempts on red chances will be 90/10 and as more attempts we have, possibility rises to win.

Let's now consider forex. First of all we must take most rangebound pairs (EURGBP, EURCHF), we have huge moves on daily charts for example skyrocket move in EURGBP by 150-200 pips in two days. We sell 1K and place 30 pips stop and 40pips take profit order. We lost! We go short with 2K again and place 25 pips stop versus 45pips take profit. We lost! we go short with 4K and place 20 pips stop and 50 take profit.
kill me if price will not reverse

So trend continuation chances are very small as we increase numbers of attempts. Pay attention that I am decreasing pips of stop loss order and increasing pips of take profit order, because as price goes up trend becomes more and more mature and there is less chance price to go up than in case of first attempt (placing 30 pips stop).

Now try to decline my idea, I will be grateful for criticizing comments
