Here are my 2cents: Robinhood is irrelevant and border line dangerous. Irrelevant, because for someone who knows what they are doing in the stock market paying $10 or $0 per trade is not going to save them any money. Dangerous, because it promotes more trades for the “unsophisticated” investor and encourages leverage = very dangerous situation. Bottom line, if you do not know what you are doing, don’t do it, buy and…

I agree with the thrust of your argument, but I'm confused with regards to ebay. I took a casual look and, yes, found listings of "financial data" (among lots of buzzy keywords) for Do you have personal experience buying data from ebay? Why would you do that?

Buying on eBay 20 years of data for $100 is a very good risk / reward for me, no offense, but data is cheap, $100 is one dinner out for me... even if the data was crap it is much better than to spend few thousands dollars for data from another unknown provider from the web with crappy result...

I use Robinhood with a small amount of money that I am 100% ok losing. I hold a small number of tech stocks to keep me invested in their movements. Some of them have turned out better (nvidia) than others (twitter). But it does help me follow the news from those companies a little better.

Please do not do this, it is never OK to loose money, better give the money to charity and sign for a fantasy portfolio and get your news and trills there...

Nobody asked about your income or whether the data was worth $100 or not. OP said he couldn't find good data on eBay and asked for clarity

Your comment is very perplexing in content and tone.

Agreed that owning stocks will keep you more engaged with what is happening in the business world, but you'll need super human discipline to not act on the news. Wells Fargo, for example, is now trading at an all time high despite being involved in recent massive consumer fraud.

I don't see how Robinhood is any more dangerous than the others. They offer the same products as regulated by the financial industry. Companies advertise all the time with x amount of trades a month/year at low or $0 cost. You can't just go in an day trade because there are restrictions and regulations on everything just as any other brokerage firm.

Any UK/EU equivalent of Robinhood (free trading, ISA support)?

There's a few in the works, but none live yet that I know of.

Also, since they're not yet live I can't vouch for them, but here's an example: https://freetrade.io/

Your 4th paragraph contains a rather bold claim. You give one counter example to buy and hold strategy being good. I imagine no one really thinks buy and hold means to never sell under any circumstance. It seems to me to be more of a philosophy that buying/selling on emotion can be dangerous. The second to last paragraph seems to me to be quite dangerous. I'd wager it is quite likely a person would see a pattern that…

As in anything in life you need to have a strategy, even if you invest only in SPY ETF you still have to have a plan when to buy and when to sell. One interesting idea to start is to look into different trend following strategies. Get the data and back test different scenarios and see what is going to work for you according to your risk management, what draw downs you can tolerate, etc...

Buy and hold indefinitely is a completely valid strategy, and outperforms almost all active investment strategies in the long term.

Sorry if I came out this way, but this is my honest answer - the data is cheap... being a lazy person, for me everything is a risk/reward... $100 to back test any trading strategy I can imagine up to 20 years back is the best risk / reward, much much, better than to go and start trading "for free" on a fancy app on a $500 phone with a "small account" I can "afford" to loose...

They offer 2x margin with the normal rules against pattern day trading with There are much better options for high-risk (reckless) trading, like 500x Forex accounts, "binary options", and lots of other nonsense enabled by offshore jurisdictions. For an easy example of how reckless/risky these alternatives are, look at FXCM/Alpari/etc after the 2015 EURCHF action.

How do sketchy offshore shops collect on negative cash balances? 500:1 leverage sounds so crazy I wouldn't be surprised if it's used as a money laundering vector.

They don't, or shouldn't have to. Brokers that offer generous margins do something typical brokers do not - they auto-liquidate when you fall below minimum maintenance margin. Most retail brokers would give you a friendly phone call and let you liquidate the next day or so.

Next, forex markets are so heavily traded they have a virtual guaranteed stop. That is, if you set the order you will get it filled no worse than that price.

The only way a broker gets hit is a sudden currency drop, like the Swiss franc did a few years back.

Especially with somewhat-diversified assets like SPYders or index funds.

At least, it's worked reasonably well for me for the last 20 years.
