You can get a sense for how much net stock @RobinhoodApp customers were buying from the size of capital RH just

The $1bn is to cover future possible activity, so it doesn't matter for looking backwards.

It does confirm that solvency concerns drove the restriction. You don't raise 1bn of equity to cover your tracks if nefarious, nor if the restrictions were a tap from regulators.
They drew $500-600m and presumably met their NSCC margin call with cushion. Say they posted $350m (guess - you don't draw $500m to post $62m and shut down trading methinks).
I did a quick guesstimate yesterday - 20m normal going to 200m on 4x VaR and 800m net unsettled buys of GME.

That ain't 350m. So either the size of GME buy and/or VaR multiple are ~2x that or DTCC demanded more than 10% margin on unsettled GME trades.
You can't get a tight range of what the net GME buy was outstanding without knowing more, but you can bound it - the net GME buy *10% < 500m so less than 5bn ... not v helpful frankly.
It's probably just as easy to ask RH custy AUM times avg GME position size ... lots of little 100% all-in, but across all of it much lower.
I know people want to focus on the short-covering as the "forced" buying that they should aim to sell into if engaged in this squeeze play. New longs coming in is likely the bigger dynamic (like any MLM scheme), not the shorts covering.
If it started 240% longs and 140% shorts, the gross is much lower now. Guess it's 150% longs and 50% short, say - that's dollar shorts up ~30x (/shr up 100x and % down 2/3rds). Put passive longs at 30%.
Under that scenario, the 120% active longs are hoping to cover into 50% shorts ... it's musical chairs. The real hope is other, more bold/wild longs arriving and taking you out higher.

Yesterday px action confirms imo that we're in this stage of the speculative attack.

हिमालय पर्वत की एक बड़ी पवित्र गुफा थी।उस गुफा के निकट ही गंगा जी बहती थी।एक बार देवर्षि नारद विचरण करते हुए वहां आ पहुंचे।वह परम पवित्र गुफा नारद जी को अत्यंत सुहावनी लगी।वहां का मनोरम प्राकृतिक दृश्य,पर्वत,नदी और वन देख उनके हृदय में श्रीहरि विष्णु की भक्ति अत्यंत बलवती हो उठी।


और देवर्षि नारद वहीं बैठकर तपस्या में लीन हो गए।इन्द्र नारद की तपस्या से घबरा गए।उन्हें हमेशा की तरह अपना सिंहासन व स्वर्ग खोने का डर सताने लगा।इसलिए इन्द्र ने नारद की तपस्या भंग करने के लिए कामदेव को उनके पास भेज दिया।वहां पहुंच कामदेव ने अपनी माया से वसंतऋतु को उत्पन्न कर दिया।


पेड़ और पौधों पर रंग बिरंगे फूल खिल गए और कोयलें कूकने लगी,पक्षी चहकने लगे।शीतल,मंद,सुगंधित और सुहावनी हवा चलने लगी।रंभा आदि अप्सराएं नाचने लगीं ।किन्तु कामदेव की किसी भी माया का नारद पे कोई प्रभाव नहीं पड़ा।तब कामदेव को डर सताने लगा कि कहीं नारद क्रोध में आकर मुझे श्राप न देदें।

जैसे ही नारद ने अपनी आंखें खोली, उसी क्षण कामदेव ने उनसे क्षमा मांगी।नारद मुनि को तनिक भी क्रोध नहीं आया और उन्होने शीघ्र ही कामदेव को क्षमा कर दिया।कामदेव प्रसन्न होकर वहां से चले गए।कामदेव के चले जाने पर देवर्षि के मन में अहंकार आ गया कि मैने कामदेव को हरा दिया।

नारद फिर कैलाश जा पहुंचे और शिवजी को अपनी विजयगाथा सुनाई।शिव समझ गए कि नारद अहंकारी हो गए हैं और अगर ये बात विष्णु जी जान गए तो नारद के लिए अच्छा नहीं होगा।ये सोचकर शिवजी ने नारद को भगवन विष्णु को ये बात बताने के लीए मना किया। परंतु नारद जी को ये बात उचित नहीं लगी।

4/ Before the arrival of recorded music, what used to be scarce was the actual music itself — required an in-person artist.

After recorded music, the music itself became abundant and what became scarce was curation, distribution, and self space.

5/ Similarly, in careers, what used to be (more) scarce were things like ideas, money, and exclusive relationships.

In the internet economy, what has become scarce are things like specific knowledge, rare & valuable skills, and great reputations.
