Obviously, this relatively rudimentary strategy shouldn't work for some reason (otherwise everyone would be doing this), and the purpose of this thread is to ask why.

Suppose we code an algo that keeps tracking the current NBBO bid-ask of a particular stock at the smallest possible time scale, and which constantly submits a bid/ask (of, say, 100 shares) at a price slightly above/below the current NBBO bid/ask. This implies our algo would be soaking all the orders that would otherwise be directed to the best market-maker.

We wouldn't be making as much profit off the spread as the best market-maker would, but we would be making some profit nevertheless (market-makers are not willing to end t

Here is the 2022 Short Interest Reporting Dates:

https://www.finra.org/filing-reporting/regulatory-filing-systems/short-interest

Today's data will cover the two-weeks period that starts on Dec 31 and ends on Jan 14. Recall that these two dates are Settlement Dates = Trading Dates + 2 business days (the so-called T+2). So it effectively covers the trading period Dec 29 to Jan 12. Data providers like Ortex and S3 will update their short interest data with these new figures.

Note that today is Jan 26, many shorts have covered part of their positions since Jan 12, and many have opened new shorts, so the data is

Ortex currently shows a CTB min/avg/max of 419% and Utilization at 97% (a drop from 100% from the previous days), while IBKR data currently shows a CTB of around 370% (Fintel too) and a few new shares available to borrow as of this morning (an increase from zero from the previous days).

Ortex has an estimated current SI of 281k shares, but this estimation is based on the official data released yesterday in the FINRA report (75k SI), which covers the two-week period that ends on Dec 31. This deadline is a settlement date (T+2), not a trading date, and all new short positions were opened on Dec 31 (which have a T+2 settlement date of Jan 4). This means that the FINRA data released yesterday d

EDIT: Regarding the official FINRA short interest report discussed at the end, Dec 31 is the Settlement Date, not the Trading Date. Copypasting from Schwab: "Settlement marks the official transfer of securities to the buyer's account and cash to the seller's account. For most stock trades, settlement occurs two business days after the day the order executes, or T+2 (trade date plus two days). For example, if you were to execute an order on Monday, it would typically settle on Wednesday." Since the short positions were opened on New Year's Eve, then their contribution to the Sh

EDIT #2: Two sudden trading halts in a row today Jan 11, the stock price shot from the $5s to the $8s.

Just got FDA’s Rare Pediatric Disease designation for cancer therapy. Float of around 1M. IPO just two weeks ago, on Dec 16 2021. Vol of around 50M during the first half hour of trading alone. This could end up bigger than LGVN.

Edit: Apparently, their IPO was 4.2M shares: https://www.sec.gov/Archives/edgar/data/1873835/000149315221032048/ex99-1.htm

I don't know how many of those are in institutional hands not willing to sell, but sources that derive their data from bloomberg quote a float of around 1M for some reason (ex: [https://www.wsj.com/market-data/quotes/IMMX](https://www.wsj.com/market-data/quotes/IMM

Third halt of the day. I'll provide an update here at some point today.

Update:

Stock just added to the Russell 2000 index. Float of 11M. Borrowing fees between 90% and 300%. No shares available to borrow since the beginning of the day. Shorts started shorting today at around 10:09am, 10:25am and 10:51am. The stock price just kept holding and going up, trapping the shorts. A/D line shows people are buying and holding. If the price action continues this way, there should be a lot of covering during AH.

Edit: 4th halt at 11:36am.

Edit2: here is a short who has already exited at a loss, and [another](https://twitt

Are people here paying attention to what's happening with ADGI today? It seems the setup that is forming is very similar to what happened with LGVN back then. The stock price skyrocketed today. A/D indicates people/funds/tutes are buying and holding. There have been no shares available to borrow since 11:30am, when that $15.5 peak formed. So shorts started shorting from there. However, the stock price does not seem to be going down significantly, which indicates shorts are probably trapped there (they cannot exit at a profit). If the stock price continues with this performance, shorts cannot exit properly and we should see some serious action during extended hours or during the ensuing days.

I've been around here since the days prog was trading below $1. I joined you in many plays, sometimes I made a lot, sometimes lost a lot. I've fended off many fake pumpers that popped up from time to time and defended and contributed to the good plays when the right technicals were there. I even wrote this introduction recently to help out newcomers.

Today offers an opportunity to provide another contribution and give back to this community once again.

Many of you remember mcad/bttx, the last SPAC/deSPAC that was subject to a real redemptions squeeze. Right after the redemption rate

This is the stock's daily short volume for the month of November:

PTPI Short Volume

As you can verify, there was a massive shorting event on Nov 3 (red arrow). This coincided with a major bullish news that sent the stock price parabolic on that day (extended hours suppressed):

PTPI on Nov 3

The setup back then was similar to that of the recent plays. However, the stock didn't squeeze (and the shorts covered), this is the char

In this thread I'll eli5 the general picture, how you can detect these potential squeeze targets, which metrics to use and what to expect. The discussion should be basic enough to allow everyone to understand the content.

Let's start with the setup, which is relatively straightforward.

Setup

The company in question is usually the object of a sudden bullish news, after which the stock price goes parabolic, typically during extended hours (AH or PM).

The few of those who originally had been investing in the stock before the news now find themselves in a profitable position. The greedy HFs and everyone else that can short also want to feast, but had no initial positions and surely aren't

Alright folks, I wanted to speak with you about something.

Currently, ARQQ is in a very strange situation. The cost to borrow ARQQ shares (in order to short) is currently extremely high, in the past few days the fees have been between 200% and 400% as you can confirm for example here (data from IBKR brokerage), you can also check Ortex if you have access to it. That's why this fellow wrote this happy thread in this sub recently. In addition to this, there are hardly any shares available to borrow for several days now (albeit that, the stock price has been

Zero shares available to borrow since Nov 24, the day the bullish news came out. Short volume increased massively on the 24th, from an average of 200K to 89.5M shares. During that day, the stock price didn't drop significantly, so the shorts couldn't cover. They are stuck since the $5 stock price, they have been trying to double down but it hasn't been working (micro-floater and social media is all over it). They will have to cover massively. Cost to borrow insta spiked from 1.3% to 136.9% according to IBorrowDesk. During pre-market today, the stock started sky rocketing.

Also a microfloater, only 3.6M shares, no options (so they cannot hedge), same industry.

Just as it happened with LGVN,
