Trading ETFs/REITs since 1998, crypto since 2016. Building TradingCalc: deterministic risk math for traders, human and AI. Check the numbers yourself.

@corwinperdomo @janwilmake Did so

@rauchg Hi folks, doing this for trading math. 43 canonical test vectors, every tool result signed with ECDSA P-256, and a daily record of the pass/fail state anchored on Solana. The agent only has to pick the right tool, the number is checked, not generated. https://t.co/kctOfRHqOX

@liquidated_hl @Blockhouse_cap @fengtality @_hummingbot funding rate arb works until everyone piles in then u need better execution than the algo next to you. btw O did a cool funding calculation tool

@LiaoMojo $120m in forced buys isn't exactly organic demand but yeah the narrative will be "bitcoin surges"

@karpathy Tried this on a calculator page. Left: our original paragraph on the Sharpe ratio. Right: the same paragraph in ASD-STE100, about 80% of the way. Same formula in both. https://t.co/f1rdnt2Loy

[Sergey Kalinin @kalinins]

It is open source and free to try: https://t.co/5xVFQfAjHt. The same maths is on https://t.co/Lq3rZEACIp, and https://t.co/gsOvDmckxR shows the test vectors passing live.

Two buys of the same size on a coin-margined contract, one at 2000 and one at 4000. The average entry is 2666.67, not 3000, because on an inverse contract the average is a harmonic mean.

A language model is built to continue text, and the plain average is the pattern it has seen most. So it can give you 3000 in a calm, confident sentence. That is 12.5% off your entry price, and nothing in the answer looks wrong.

This is what I run into whenever a model is asked for exact trading maths. It was not built for that, and its mistakes look like answers.

So I stopped asking it to calculate. The model asks, a server does the arithmetic, the same input always gives the same number, and every result is signed so I can check that it came from the formulas and not from the model's memory.

@3ExpressoShots @AnnaEconomist how many times do we need to watch this movie before someone actually gets prosecuted

[Sergey Kalinin @kalinins]

@SOntheotherside good luck, mate :)

[Sergey Kalinin @kalinins]

@SOntheotherside this is why people blow up. hedge costs money upfront, u get impatient and pull it, market moves anyway. rinse repeat

[Sergey Kalinin @kalinins]

@fomoebdao @Crypto_Pranjal @TxFlow_L1 built a calc for this exact combo actually. the math works til it doesn't

@solamihunter @therealchaseeb @joinfrontier 500x is just a slower way to donate to the exchange

[Sergey Kalinin @kalinins]

@CryptoLab_1 lol robinhood choosing the boring route. never bet against them picking safer over faster

[Sergey Kalinin @kalinins]

@SOntheotherside loan account mooning while shorts get rekt, classic. yeah ai beats manual stops every time

[Sergey Kalinin @kalinins]

@714_Wolf22 @Bobby_1111888 had to learn the hard way. at least u know the lesson now instead of doing it three more times

[Sergey Kalinin @kalinins]

@onlyonerax leverage is a hell of a drug

[Sergey Kalinin @kalinins]

@riskoff_hl @binance @bitget what a day. binance finally adds spot after sitting on perps, bitget got rekt, and btc takes a 10yr yield beatdown

[Sergey Kalinin @kalinins]

@bnuggsi weekly close decides everything, options just bleed you dry while you wait :)

@Marianna_805 @AshCrypto liquidations are how the market teaches expensive lessons to people who think they have it figured out
