The daily-close-above-50-day filter that turned a BTC 4-hour breakout rule from +1.2R into +19.4R was run unchanged on ETH and SOL, January 2022 to September 2026. ETH: -14.4R became -5.8R, and a random filter did as well 35% of the time. SOL: +3.8R became +9.3R on only 26 trades. Plus the hidden 6% stop limit that removed 80% of SOL breakouts. https://tradingprimer.com/portfolio/coins/ethhttps://tradingprimer.com/portfolio/coins/ethFri, 09 Oct 2026 04:00:00 GMTEthereum checked against all 8 SuperShark Cycle criteria: #1 by TVL ($50.9B), 48% of stablecoins, $4.62B of app fees a year, staking with a three-week exit. Buy zone $1,487.02 to $743.51; the $1,505.35 low missed lot 1 by 1.2%, so 0 of 10 lots filled. https://tradingprimer.com/what-is/trend-filterhttps://tradingprimer.com/what-is/trend-filterWed, 07 Oct 2026 09:30:00 GMTThe same 20-bar breakout rule on BTC/USDT 4-hour candles, January 2022 to September 2026, with nine trend filters. The textbook daily-close-above-200-day filter cut trades from 122 to 69 and turned +1.2R into -1.7R: it skipped the 2022 losses and the start of the 2023 rally. The 50-day version made +19.4R, but the 150-day made +0.5R. How to test a filter without fooling yourself. https://tradingprimer.com/portfolio/coins/solhttps://tradingprimer.com/portfolio/coins/solWed, 07 Oct 2026 04:00:00 GMTSolana checked against all 8 SuperShark Cycle criteria: #1 by DEX volume, #2 by TVL, staking with a two-day exit, $314.15M raised, 22% of Ethereum’s market cap. Buy zone $88.72 to $44.36; the $60.11 low filled 6 of 10 lots. https://tradingprimer.com/what-is/hindsight-biashttps://tradingprimer.com/what-is/hindsight-biasMon, 05 Oct 2026 09:50:00 GMTEvery 20-bar breakout on the BTC/USDT 4-hour chart from January 2022 to September 2026: 122 trades, 25.4% reached a 2R target and the rule netted +1.2R before fees. The ten breakouts that ran furthest made +17.0R; the other 112 lost 15.8R. On the entry bar, winners and losers looked the same, volume included. How to practise without the right side of the chart. https://tradingprimer.com/portfolio/guide/why-top-layer-1s-firsthttps://tradingprimer.com/portfolio/guide/why-top-layer-1s-firstSun, 04 Oct 2026 16:20:00 GMTFrom the first buy in the zone to the next cycle high took about three years for BTC, ETH, SOL and BNB. Staked at today’s rates, the coins bought would have grown 7.1% (ETH), 14.9% (SOL) and 3.4% (BNB); on Solana that lifted 5.3× to 6.1×. https://tradingprimer.com/portfolio/guide/lessons-from-the-last-crashhttps://tradingprimer.com/portfolio/guide/lessons-from-the-last-crashSun, 04 Oct 2026 14:45:00 GMTCourse rules re-run on nine leaders: BTC fell 77.6%, AVAX 92.8%, AAVE 93.1%. AVAX bought on its own −85% to −95% zone returned 4.2×, versus 2.1× on a top-L1 zone; Bitcoin filled 5 of 10 lots and still returned 6.9×. https://tradingprimer.com/what-is/runs-testhttps://tradingprimer.com/what-is/runs-testFri, 02 Oct 2026 09:40:00 GMTA 45% win-rate journal has a 46.5% chance of six losses in a row by pure luck in 50 trades, so a streak proves nothing. The runs test does: it caught real clumping (a loss after a loss 70% of the time) in 75% of 50-trade journals. When losses clump, halving size after three losses cut the chance of a 50% drawdown from 24.7% to 2.6%; when they do not, it cost median growth. https://tradingprimer.com/market/2026-10-02-daily-briefhttps://tradingprimer.com/market/2026-10-02-daily-briefFri, 02 Oct 2026 03:30:00 GMTBitcoin near $85,368, up 2.21% in 24 hours and sitting on its 24-hour high, with Ether at $2,724.15 and Solana at $120.30. The Binance perpetual book grew 4.9% off Tuesday’s low while the share of accounts holding longs fell from 58.76% to 50.38% in nineteen hours, funding stayed below its 0.0100% resting rate for a twenty-ninth settlement running, and US spot Bitcoin ETFs ran $144.4 million of net outflow over the same stretch. https://tradingprimer.com/market/2026-09-28-daily-briefhttps://tradingprimer.com/market/2026-09-28-daily-briefMon, 28 Sep 2026 00:30:00 GMTBitcoin near $84,425, up 0.03% in 24 hours, with Ether at $2,686.59 and Solana at $121.91. US spot Bitcoin ETFs took $2.4 billion in the week to 25 September — their strongest since October 2025 — but daily inflows decayed from $999 million on Monday to $134.5 million on Friday, while the Binance perpetual book fell 14.8% from its Monday peak and funding never once reached its resting rate. https://tradingprimer.com/what-is/dexhttps://tradingprimer.com/what-is/dexSun, 27 Sep 2026 12:30:00 GMTA DEX never holds your coins. That one fact decides who can freeze, lose or return your money — and the honest version has two exceptions: Circle’s USDC terms reserve the right to block an on-chain address, and on Hyperliquid the validators sign and send every withdrawal. A swap pool and a perp venue charge in different shapes; their fee lines cross at about a $196 ticket.

Sized as one 2% cluster (0.67% each) it fell to 0.02%.

Binance Bitcoin perpetual open interest fell 12.9% — 14,198 contracts — across 68 hours in which price fell 1.1%, and funding printed below its 0.0100% resting rate in ten of the last twelve settlements. 25 Sep 2026 brief. https://tradingprimer.com/exchanges/availability-by-countryhttps://tradingprimer.com/exchanges/availability-by-countryThu, 24 Sep 2026 13:00:00 GMTBinance, Bybit, OKX and Kraken checked across 12 countries on three layers: account, local currency and derivatives. Only 22 of 48 venue-country pairs clear all three. All three offshore venues exclude Canada, yet 88 Canadian-dollar adverts sat on their P2P boards. https://tradingprimer.com/dex/self-custody-checklist-before-first-dex-tradehttps://tradingprimer.com/dex/self-custody-checklist-before-first-dex-tradeThu, 24 Sep 2026 11:00:00 GMTOn Hyperliquid, 4 of the 5 wallet prompts that can cost you money are gas-free signatures.

Three points of error in your win rate and full Kelly shrinks the median account to 0.77x on a profitable system.https://tradingprimer.com/exchanges/lowest-fee-crypto-exchangehttps://tradingprimer.com/exchanges/lowest-fee-crypto-exchangeMon, 21 Sep 2026 12:40:00 GMTA flat withdrawal fee and a percentage trading fee cross over at about $1,500: below that the withdrawal is 88% of the bill, above it 7%. The same $200 cost $5.70 the default way (card, market order, Tron) and $0.24 the informed way on the same exchange on the same day — and the 0.10% rate every comparison quotes was 3.5% of the total. Across the ten USDT networks Binance and OKX both publish, OKX is cheaper on seven and Binance on two, with a 1,600-fold gap on Plasma. Bybit publishes no withdrawal fee before you open an account.

Left as a market order a stop carries a documented 10% slippage tolerance — $1,000 on a $10,000 position, 222 times the $4.50 taker fee. Invert the venue’s own liquidation formula and the stop distance you want becomes a leverage ceiling: 5% needs 16x or less, 10% needs 8x or less, 20% needs 4x or less. Above 8.99x on BTC — 6.90x on 10x-cap assets — the slippage band is wider than the entire distance from entry to liquidation. Official docs, read 20 Sep 2026.
