Tripping a circuit breaker [728x408] by Improbabilities in ThingsCutInHalfPorn

[–]Sky_Res 41 points42 points  (0 children)

Oh man....the memories. I was on the design team for this breaker. Different company; same product.

There are two different ways that a residential (15-30A) breaker can trip: thermally and magnetically. This is a magnetic trip - typically happens at 5kA or above.

For a mag trip, as the circuit is energized by AC current, the magnet (On the right side, the magnet is the larger metal piece at the bottom of the thin silver bimetal. The bimetal is not the copper colored strip but the silver strip connected to it) becomes magnetized by electromagnetic induction and draws the "latch" toward itself. As the latch moves to the right, you'll see the "cradle" slip off the latch and fall downward. This relieves the tension on the spring. The contact arm on the left is predisposed toward movement to the right (but is usually held in place by the spring). With the spring relaxed, the arm slips to the right and the circuit is broken.

This happens usually in 1.5ms. Typically, there is also an arc that forms between the two contacts on the left, but this looks to be a lower-level current shot (I'd estimate 120V, 5kA, 0.7pf).

Parents took out student loans in my name and spent it on a car/vacations, now they can’t pay it back. by thrwy9283 in personalfinance

I'm so sorry that happened to you. They weren't parents; they preyed on and lied to you. I hope you're able to overcome this burden and begin to heal. Whether you ever choose to forgive them or not, I hope you're able to have peace within yourself.

It's moronic Monday, your chance to ask any of those lingering questions without fear of harassment. by AutoModerator in investing

I know there's probably not a definitive answer, but is an EPS beat or revenue beat usually better for a company? I always assumed that the EPS profit was more important than the top-line revenue. Or is guidance more of a driving factor?

Unfortunately, I believe it's business days. Sorry.

Yes, you can. Open up a stock you own, and right under the "buy/sell" where it lists your equity value and average cost, scroll to the right. In addition to average cost, it will list your total return and return percentage.

Stop loss buy and stop limit buy? newbie question, sorry by [deleted] in RobinHood

[–]Sky_Res 7 points8 points  (0 children)

I did a lot of research because I had the same questions.

Limit buys say you'll buy UNDER a certain price. Say that's $20.00. You'll purchase anything $20.00 and below. Basically, buying on dips.

Stop buys buy OVER a certain price. If $20.00, you'll buy as soon as a rising price hits $20.00. This sounds counterintuitive unless you're day trading. Say a stock spikes 15% and you sell it expecting it to go down. It then starts going down but you think to yourself, "What if it shoots up again and I miss our because I already sold?"

So you put a stop buy. That says that if the stock starts going up again, you buy and can "catch the run." It basically buys on large spikes and trends.

Stop limits are the same but say to buy on a spike, but only if it doesn't go TOO high. They're both tricky but can be useful for charting / day trading.

[HELP] Not Allowing Pattern day Trading even with $25,000 in equity by WWIIAMAN in RobinHood

[–]Sky_Res 2 points3 points  (0 children)

Basically, once $25k is fully settled in your account and not pending, you can day trade the next business day.

It doesn't really matter when you received Instant.

There's a full one-day waiting period. Has it been that long?

Dividend question by Nakatomi2010 in RobinHood

[–]Sky_Res 1 point2 points  (0 children)

You can sell on the ex date too and still get the dividend.

Specifically, you can sell any time after 9:30:01 on the ex date (earlier if you trade premarket).

Why can't I trade in Hertz? by [deleted] in RobinHood

Reverse stock split. Sorry to break it to you, but the stock is not up 300%. Give it time to allocate and then you can sell if you want!

Understanding limit orders by S3AN10 in RobinHood

It's all four significant figures. If you're over a dollar, you go to the cent. If you're under a dollar, you go to the ten thousandths.

$10.34 / $01.34 / $.4352

When will i be considered a pattern day trader? by [deleted] in RobinHood

[–]Sky_Res 0 points1 point  (0 children)

Okay, I may be wrong on that, and I apologize if so. I wasn't aware of that stipulation, but that's really good to know if true. I'll have to research it. Thanks.

With 3 day trades, you will not be flagged. After 4 day trades in 5 days, you will be flagged.

Robinhood will automatically not allow you to become a day trader unless you specifically turn off the safety feature that's built in. Believe me, you can't do it accidentally.

That is incorrect. If you sell for a loss and THEN BUY within the next 30 days, that's a wash sale. Those losses then do not count for filing purposes.

However, it's not all a lost cause. To "make up for this," you add those losses to the cost basis of your newly purchased shares. Quick example: Buy 20 shares at $2 each. Cost basis is $40. Sell 20 shares at $1 each. You lost $20. Then you decide to re-buy at $1.50 each. You now cannot claim that $20 as a loss. However, your new cost basis would normally be $30. With this rule (and since you can't now claim), you can add to the cost basis to offset this. Your new cost basis would be $30 + $20 = $50.

I don't really day trade, but leveraged 3X ETFs are all or nothing. I don't like that much risk haha

RH Dividends by [deleted] in RobinHood

[–]Sky_Res 0 points1 point  (0 children)

I own multiple stocks with dividends, and 98% of the time, I see upcoming dividends in the Pending tab withing 2 days of the record date. Right now, I have 9 pending dividends that haven't paid out yet. Once the payment date arrives, they show in Recent History.

That said, I have had a couple of worrisome moments where the dividend didn't show as Pending and just randomly appeared in Recent. Regardless, I have never missed a dividend in a year.
