I said I'd reply to
@cwhaley so here's a bit:
If you pick a London market stock which tiy think will, or has already, done well...
This called an ETF. It's 5x the US Tech sector top 100...
There's no fuss with exchange rates - it's all in the price.
It's not a a share as such, so there's no stamp duty, and there's no CGT.
Pick a cheapo platform and there are no other fees. They shave the bid/offer price but you won't even be aware of it.
This is May to now:
Those candles are 4 hours wide. Ignore the lower trace & boxes, for now...
Any stock with an up-trend will do. Of course you can switch around between your favourite runners as much as you like. There no fees, bid/offer would be maybe 0.1% but it's invisible.
What they do is use complex "instruments" to get you this return, but it turns out to be directly what it says.
If you watch it, and, say, buy at the blue candles and sell when two decent sized, or 1 huge, red come along. Then you buy back when there are 2 blue.
That lousy but simple strategy produces a couple of cases near the start that don't do much, but as it goes on you miss out most of the drops. I accumulated the cut out parts, ( which is the lower trace+boxes) which comes to half a chart height, so what's showing here as 220% rise, would give over 300%.
To prevent a disaster you can put a "stop loss sell" a couple of squares below the current level as it goes up. So if the market collapses (that's USA collapsing) you shouldn't lose too much. If you wanted to, you could sell every Friday night and rebuy on the Monday, but you wouldn't gain as much.
You can use a phone app to alert you, but if you only checked once a day there's nothing here that would have cost you too much.
You can buy a load on individual "instruments" for one stock, like Apple, Google etc, as 1X, 2X and 3X, and also -1X. -2X, and -3X so you gain when the stock price drops. You caould al;lternate between
+ and
- ETFs.
There are lots of other ways, but this sort of stock, on a free platform, free of exchange fees, taxes and fluctuations, makes it simple.
You need a long-lasting trend. We may be nearing the end of this one. You can work from weekly, daily or minutely trends, but that's harder work.
I suppose I need to add that stocks don't often have a run like this one for an extended period.

Edit
Mottie should be able to understand. I know JohnD and others wouldn't, but that's a low bar.
The aim is to hold the thing while it's going up, and flog it when you see it turning down.
The "candles" are red when the price goes down in the period denoted by the width of the candle. You can set 1 minute, one hour etc.
Blue when it goes up.
The wicks of the candles show you more but I'm keeping it simple.
If you get two ups in a row, it's likely to continue up, and vice versa. So you can use those to tell you when to buy and sell. I chopped the bits out of the trace above for when you wouldn't own the stock, and put them connected together so you can see the effect of not owning the stock for that time.
