Паттерн Декоратор — специальный способ организации модулей в программе, который позволяет подставить какую-то новую функцию прямо в середину цепочки вызовов, тем самым чуть-чуть подкорректировав поведение.
Например, в реальном мире очки для чтения это декоратор. Вы ставите их между вашими глазами и текстом. Глобально взаимодействие ваших глаз и текста не меняется: отражённые световые лучи от страницы книги попадают в ваши зрачки, что с очками, что без них. Но очки располагаются посередине: они принимают лучи на вход и преломляют их, передавая дальше вам в глаза уже изменёнными.
Важной особенностью является тот факт, что очки можно снять. Они не требуют ни модификации вашего тела, ни модификации книги. Вообще никакие условия не нужны, кроме наличия самих очков. А если вы в линзах, то внешний наблюдатель может даже этого не знать.
Класс-декоратор должен быть спроектирован так, чтобы не требовать никаких изменений в объектах, с которыми он работает. Его можно отключить, чаще всего буквально закомментировав одну строку.
В примере ниже программа выведет текст "Привет, мир, в натуре.", и вот это дополнение в конце как раз дописано декоратором. Можно убрать или закомментировать подчёркнутую строчку, не трогая остальной код, для всех внешних вызовов сигнатуры останутся теми же самыми, но выводиться будет уже просто "Привет, мир".
В декораторы можно прятать логику, которую буквально навешивают поверх основной функции программы. Например, проверку прав на выполнение операции. Перевод на другой язык, логирование, поддержку обратной совместимости при обновлении и так далее.

Prop Firms in 2026 – The Ugly Truth
1/ Many traders pass challenges after many attempts and after long path of learning and then practicing and winning it after multiple failures…
then get payout denied or rules suddenly changed once funded.
This is the worst pattern right now.
2/ Hidden Rules That Appear ONLY at Payout
- Consistency rule (15-35%) kicks in funded only
- News trading ban (5-10 min window)
- Leverage drop & daily profit caps
- Risk-per-trade limits (2-3%)
All invisible during the challenge.
3/ Classic Bait-and-Switch
Challenge = full news + weekend holds + no consistency
Funded = new restrictions + extra monitoring + profit deductions
4/ Payout Denials Are Rising
Small payouts = fast
Big payouts ($3K+) = sudden “review”, IP flags, copy-trading accusations, or vague “abusive pattern” excuses.
Same strategy that got approved 5 times suddenly gets denied on the 6th.
5/ Hidden Swaps + Slippage Traps
Real swaps eat your equity on weekend holds.
Bad fills push you into drawdown.
Many firms still not truly swap-free.
6/ Bottom Line
Read every rule before paying.
Demand firms with zero consistency, identical rules challenge-to-funded, and real swap-free.
Test small. Trust verified payouts only.

📉GBP/USD – Bearish Pressure Building!
The pair has finally broken below its rising channel on the H2 timeframe, confirming exhaustion near the 1.2700–1.2720 supply zone. Price action is now showing signs of momentum shift, with lower highs forming and downside liquidity becoming the primary target.
🔎Technical Outlook:
• Rising channel breakdown ✅
• Rejection from higher timeframe resistance ✅
• Clean liquidity pool resting near 1.2480 support ✅
📰Fundamental Outlook:
The U.S. Dollar is gaining strength as markets price in the Fed’s hawkish stance and resilient U.S. data, while the British Pound remains pressured by weaker U.K. growth prospects and persistent inflationary concerns. The divergence in monetary policy continues to favor USD strength.
⚠️Bias: Bearish – Short-term downside remains likely unless buyers reclaim 1.2700 with strong volume.

Bitcoin Mining Ban and Market Resilience

Data from PumpFun reveals that only 0.4% of meme coin traders made over $10,000, while 60% ended with losses. Most users either broke even or earned little.
