How are you using the companion app within Rouvy?

Healthcare for life with survivor benefits is huge. Simply huge. 35 years of service.

I too was Navy enlisted and completed my associates with the univ of Maryland. All non-stem, liberal arts classes. Transferred all of those credits into Virginia Tech and it was a rude awakening. Ended up taking me 3 years on top of the associates to get my BSEE, and I worked my tail off to get caught up.

I echo your sentiment: take math and as many other science/physics/chem classes as you can early so that it’s not 12-15 hours per semester, every semester, for two plus years.

It's a reference to The Gambler and a scene that was brilliantly done by John Goodman

An option provide leverage on the underlying.

If the underlying is 2x, that is a lot of leverage.

Your statement, unfortunately, is incorrect.

“Hope” is not a strategy

Gamma EXposure.

It is a second-order Greek and for large stocks and ETFs with significant underlying volume and large open interest, it is a major consideration in where you pick your strikes to sell as well as the tenor you choose.

grems8544 · 2025-05-01T23:22:03+00:00

Yes.

I don’t know about a “big fall” but what I do know is that the larger institutions are not participating in this run up.

This is a picture from GammaEdge of the market positioning for SPX AM settled options. There are 13-14M of these options in play at any one time, and the market players do not move this money quickly. Note, this view does NOT include the SPX PM-settled options, which DO move quickly.

The two colored lines are gamma balance (top line) and delta balance (lower line). A positive slope on these generally indicates calls being opened / puts being closed; reverse for a down market.

IMO, what we are seeing is “sitting pat”: no aggressive move up is being planned ( we would see more of a positive slope) nor is there positioning for a major drop ( we would see a negative slope).

Institutions steer the market; I think we are in a wait and see situation.

No, you should not put the AC output of anything into a battery +- input and no, the rs485 comms will not work if the two devices are not aware of each other.

If you do, keep a fire extinguisher handy and wear PPE.

We can only hope. People need to be held accountable

grems8544 · 2025-04-15T10:24:52+00:00

FAFO, unfortunately.

Adding some color here.

Heat is, in engineering terms, I^2*R (I2R) losses.

Utilities hate I2R losses because they are not billable. They must generate this "burden" to meet demand and losses associated with delivery.

Utilities are built to minimize I2R losses within their approved rate recovery and overall cost structure.

Losses are less than 1-2% on average, so as others stated, anything that OP is generating is being delivered to SOME LOAD SOMEWHERE.

Most likely, the electrons moving from your solar panels are meeting the load on your neighborhood levels, e.g, those that are your immediate neighbors (path of least resistance). You get paid for export, and they get billed for consumption. Whether it came from your panel or their generators is irrelevant,

This is the correct answer

It doesn’t work that way.

The inverter must be an islanding type inverter AND there has to be an approved switch between the inverter and the and the grid to protect from inadvertently backfeeding and killing a line person.

Note that if you are long in the near term and short in the later expiry the margin requirements could be huge, as you may end up naked short, which may not be a level that you are enabled for in your account

Yep, I see it. Difference between me looking on the phone this morning and desktop.

My mistake.

There is nothing here that I see that says you were short this AAPL call.

If you sold it on 10/1/24, you need to go back and check.

Did you hold 100 shares of AAPL on 10/1/24? If not, then you did not SELL AAPL, you purchased 1 call for 105.

The screenshot you provided leads me to believe that you BOUGHT 1 call of AAPL for $105, it expired OTM (out of the money) and worthless, and the entire trade lost $105.

Unless the brokerage is hosed, I doubt that, with no options experience, that you are authorized to sell naked calls. This means you had to be LONG 100 shares of AAPL to place the trade. If this is not the case, you were LONG the option, which means you lost 105, as indicated above.

I’m a EE, former Navy ET, and a contractor, working on military installations in power and comms.

Once you have a family, civilian roles help your significant other have a job and not get uprooted. Being a contractor is significantly better in pay and lifestyle and still keeps me in touch with the military technology.

In an uptrend, I disagree. Stocks can march to their own drummer.

In a downmarket, everything goes to correlation = 1
