My thoughts on [FB] and its net effect on the prices in the market or sector technology sector

Well apparently the correlation showed up. Its just that they both moved in the wrong direction.

No, selling low and buying high is a terrible idea. I'd say he should examine whatever funds he's invested in and look to move into broad index funds with low fees. Vanguard funds are excellent. The entire market has been a bit low recently, so its not surprising that he's "lost" money.

I have a hard time imagining someone coming into a dealership saying "yeah, I want to sky dive with my car, so I need the Chevy Sonic."

They're not trying to make people think you can sky dive with your Chevy. They're trying to make you subconsciously associate a given emotion with their car. What kind of emotions does skydiving evoke?

Adventure, excitement, speed.

The more emotional you are, the more irrational decisions. Someone isn't going to walk into a dealership wanting to skydive with their Chevy, but they may be 5% more likely to buy it because thinking of a Chevy gives them a sense of adventure that they can't quite place.

Now, it may be ineffective, or less effective than a more well-thought advertisement, but its not mysterious what they're trying to do with it.

Neural networks are one amongst a variety of machine learning techniques, and are not the most popular ones. Machine learning techniques are probably used for fraud detection (and are where I work), but identifying them broadly as neural networks is oddly specific and likely signifies that the person writing the quiz was out of their depth on that question.

No idea, I'm mostly new to this too, and just imparting what I've learned so far. Needless to say, I haven't traded in penny stocks.

Ok. I was aware of the percentage thing. I was thinking of taking a backtest of an algorithm, finding the theoretical edge, W/L ratio, and win rate, then using the Kelly Criterion to figure out the size of each trade, and then applying some percentage on top of that amount to determine my potential stop-loss.

As far as the trading accounts go, I have my retirement accounts separate from my non-retirement accounts, but within my non-retirement money I don't have any separation between long-term and trading holdings. Its a good idea.

Ah makes sense. I'm looking at automated trading myself and trying to assess the things I need to know and watch out for. Thanks for the reply.

Is there any good guidance on what should constitute a small loss? I'm currently trying to absorb information on risk management, edge, Kelly criterion, etc.

I was mostly being facetious. If they actually did this, it'd be time to sell, in my estimation.

It looks like its at the end of its pump, at .64, so hopefully he's looking at getting out. If he gets out now its 6% profit.

Then they can offer Facebook Premium to remove those annoying ads.

Well, you certainly have cahones. It looks like .32 is where the stock usually trade, which means your downside potential is (.60 - .32) / .60 = 46% Ouch.

Disclaimer for this next part, don't trade penny stocks, you're being too risky yadda yadda.

I know your mindset is usually to let winners ride, but you probably need to rethink that when it comes to trading into low volume stocks that are being heavily manipulated. I think a more prudent strategy would be to define a modest amount of winnings that you'll take. If you go for the big win, your risk of getting caught in the dump phase skyrockets. Its probably better to focus on getting modest, consistent wins and rely on compounding to get your winnings over time to add up.

Edit: Actually going off of Google finance, looks like its .21 as what you can expect it to return to, which is worse.

The total number of up votes and down votes displayed by RES are not accurate anyway. Reddit fudges the numbers so that the total score is the same but the number of votes is different in order to discourage bots.

That's a nice return.

Good luck. How much did you make off the last one?

Actually, scientists found a way to bend gamma radiation in an experiment, and speculate that it may be able to help with the nuclear waste problem, and the news reported that speculation. Keep in mind that scientists usually throw out a few speculative practical applications in order to justify their research in the media. It doesn't mean that it will work out that way, nor that it will materialize in a reasonable timeframe.

He could have phrased it more politely, but the point stands that if you're not capable of doing the initial legwork and figuring out a starting point, then you should be asking yourself if you're ready to write automated trading software. It suggests some level of inexperience with writing complicated software systems or trading.

OptionsHouse, Interactive Brokers, and TD Ameritrade all have APIs. nogoodnameideas also gave a bunch of good resources.

My experience was that Vanguard's email customer service sucked. I wrote a specific question pertaining to my wife's residence status and some Roth IRA accounts and contribution limits and got a canned response back that basically ignored what I had asked. Called their phone number and got good service. Maybe its just the email CS that sucks?

Find a broker that offers an API. Program against the API in your favorite language. You can also find trading platforms that integrate with a backend API that you can build strategies on (basically, they provide all the plumbing).

ar01 · 17 days

Any reason you wouldn't do the programming yourself? Your other posts indicated that you seem to have some familiarity with programming (you mentioned running a site).

Not trying to be snide, I'm thinking of writing a trading bot myself, but I'm still green to both investing and trading, so I'm in my "information gathering/learning" stage.

Makes sense. Thanks for the info.

I must be missing something with MT's fundamentals. Investment-wise it looks to be in a pretty good shape overall despite having lost money in Q4 2011, but the price has been steadily going down over time. Whats your take on that?

DickTrickle · 17 days

I have accounts at both, and the Vanguard one comes across as no-frills compared to Schwab. I'd say keep Schwab as a bank. You might want to get a Vanguard brokerage account if you're interested in Vanguard funds. Personally, I like Schwab's web site better, but prefer Vanguard funds. My 401k and Roth IRA are both with Vanguard and I've used Schwab up until now more for stock-picking style trades/investments.

I'd be less interested in live streams and more interested in recorded videos with commentary added in. Pause the video, mark indicators, explain what they mean for a trade.

Possibly add in a newbie series where you go over basic details.
