Впервые сделал крупный проект (под NDA, так что не расскажу, какой) на облачных функциях. Впечатления противоречивые. Изначально программисты арендовали компьютер в датацентре: или целиком или кусочек. На нём теоретически можно делать что угодно, но для запуска своих программ нужно было настроить операционную систему, безопасность и авторизацию, установить нужные исполнительные модули, программы для удобства деплоя, мониторинг нагрузки итд. Поэтому появились сервисы, которые это всё делают за тебя, а тебе дают буквально окно, куда можно написать свой код и запускать его удалённо на чужой машине. Конкретно я пользовался решением от Яндекса, чей протокол скопирован напрямую с Amazon Web Services. Причём, в документации не только открыто об этом говорится, но ещё и в некоторых местах перенаправляют на доки от Amazon. И SDK предлагают тоже использовать амазоновский. До санкций я бы сказал, что это не так плохо — можно использовать что-то привычное тем, кто уже работал с Amazon. Но сейчас привязка к американскому сервису выглядит скорее жирным минусом. Не знаю, есть ли у Яндекса ресурсы на какое-то серьёзное разделение. Судя по состоянию документации и платформы в целом — нет. Yandex Cloud кажется системой, которая активно развивалась несколько лет назад, а сейчас подзаброшена. Среда выполнения .NET отстаёт от актуальной на две версии (3.1 вместо 6, четвёртой версии не существует). Изначально мой проект был написан как обычное контейнеризированное приложение на .NET 6, а потом я переводил его на функции. Пришлось пройтись по всему коду и переписать несовместимые куски с C#10 на C#8, это было не слишком приятно. Документации фактически нет, а там, где есть, много путаницы. В примерах написано одно, по факту другое: например в функцию вместо объекта Request приходит просто строка, а разбирать её надо самому. Авторизацию я нашёл только на Stackoverflow. Интересно, что адекватных доков про неё не было ни у Яндекса, ни у Amazon. Функция выполняется и выгружается, поэтому ваша программа не должна рассчитывать на наличие постоянно живущего процесса. Мне пришлось вытащить из неё большой словарь, который грузится при старте, и положить уже подготовленные данные из него в Object Storage — это такое горячее файловое хранилище, там же рядом с функциями. Справедливости ради, работает это всё быстрее, чем я думал. Удалось запихнуть в функции даже сравнительно большой проект с кучей классов, создающий при запуске несколько десятков объектов и производящий загрузку из сети с декомпрессией. Другой важный плюс — бесплатная квота довольно внушительная: миллион вызовов и 10Гб*часов оперативной памяти в месяц. Для пет проекта вы сможете вообще не покупать сервер. Но если сервер у вас всё-таки есть, деплой вы уже настроили, то удобнее будет, конечно, делать как привычно. И гибкости больше. #dev

📈Bullish Pattern - BULLISH ENGULFING A. How to recognice it? • There must be a preceding downtrend. • A shorter red candle followed by a longer green candle. • The green candle opens lower and closes higher than the red candle, completely engulfing it. B. What is the psychology behind? • The red candle implies the control of the bears following a prolonged downtrend. • In next session, the market opens below the low of the red candle, suggesting continuation of the bearish forces. • The bears then lose momentum, the bulls take charge and lead the price up during the session, and eventually manage to close above the high of the red candle. • The bulls have now fully overridden the bears. C. How do we trade it? • Look for the Bullish Engulfing at the bottom of a downtrend. • Wait for the next candle to close above the high of the green candle to confirm the existence of bullish force. • Open a long position upon confirmation. • Place a stop-loss below the low of the green candle. #patterns

📉 Bearish Pattern - Tweezer Tops. A. How to recognise it? • There must be a preceding uptrend. • A green candle followed by red candle. • Both candles have the same high. B. What is the psychology behind? • The candles in both sessions form the same high, suggesting that the market refuses to go above that price level. Once the price touches the ceiling, in retreats. That price level may be viewed as a short-term resistance. • The closing price of the red candle shies away from the high further than the green candle does. It shows that bearish forces are getting stronger. C. How do we trade it? • Look for the Tweezer Top at the top of an uptrend. • Wait for the next candle to close below the low of the two candles to confirm the existence of bearish force. • Open a short position upon confirmation. • Place a stop-loss above the high of the two candles. #patterns#fibonacciacademy

How to recognise it? • There must be a preceding uptrend. • There consecutive long red candles observed. • The second and third candle opens within the body of the preceding one but closes lower than the preceding one. B. What is the psychology behind? • The first long red candle signals that the bulls are exhausted after the prolonged uptrend and the bears start to take over. The bears continue the slump with the subsequent two candles closing lower. C. How do we trade it? • Look for the Three Black Crows at the top of an uptrend. • Wait for the fourth candle to close below the low of the third candle to confirm the reversal. • Open a short position upon confirmation. • Place a stop-loss above the high of the first red candle. #patterns#fibonacciacademy

📉Bearish Pattern - Gravestone Doji A. How to recognise It? • There must be a preceding uptrend. • It looks like an inverted T letter. • The opening, lowest and closing price are same. • It has no real body but a long upper shadow. B. What is the psychology behind? • When the market opens, the bulls push the price all the way up, resulting in a long upper shadow. • The bears fight strongly and eventually manage to drag the price back down to the opening level. • The longer the upper shadow, the more effective the bearish signal. It tells us that the bears are strong enough to conquer the bulls who once drove the price so high. C. How do we trade it? • Look for the Gravestone Doji at the top of an uptrend. • Wait for the next candle to close below the low of the Gravestone Doji to confirm the existence of bearish force. • Open a short position upon confirmation. • Place a stop-loss above the high of the Gravestone Doji. #patterns#fibonacciacademy @fibonaccisyndicate

📈 Bullish pattern - Tweezer bottom. A. How to recognise it? • There must be a preceding downtrend. • A red candle followed by a green candle. • Both candles have the same low. B. What is the psychology behind? • The candles in both sessions form the same low, suggesting that the market refuses to go below that price level. Once the price touches the floor, it bounces back. That price level may be viewed as a short-term support. • The closing price of the green candle shies away from the low further than the red candle does. It shows that the bullish forces are getting stronger. C. How do we trade it? • Look for the Tweezer Bottom at the bottom of a downtrend. • Wait for the next candle to close above the high of the two candles to confirm the existence of bullish force. • Open a long position upon confirmation. • Place a stop-loss below the low of the two candles. #patterns#fibonacciacademy

🌎 In the Namib Desert, strange circular patches called “fairy circles” appear in the grass, forming patterns seen from the air. Scientists suspect termites or plant competition cause these barren rings, which can measure 2 to 15 meters wide and last for decades. ✨ #desert⚡#phenomena⚡#patterns 👉subscribe Interesting Planet 👉more Channels ​

🌎 The Namib Desert is home to the world’s oldest living desert fairy circles—mysterious bare patches of earth surrounded by rings of grass. Scientists believe termites create these strange patterns by eating plant roots underground, shaping the desert’s landscape for centuries. ✨ #Namibia⚡#patterns⚡#termites 👉subscribe Interesting Planet

📉Bearish Pattern - Dark Cloud Cover. A. How to recognise it? • There must be a preceding uptrend. • A green candle followed by a red candle. • The red candle opens with a gap-up and closes at 50% or below of the real body of green candle. B. What is the psychology behind? • The green candle implies the control of the bulls following a prolonged uptrend. • In next session, the market opens above the high of the green candle, suggesting continuation of the bullish forces. • The bulls then lose momentum, the bears conquer and send the price down during the session, and eventually manage to wipe out 50% gains or more from the previous session. C. How do we trade it? • Look for the Dark Cloud Cover at the top of an uptrend. • Wait for the next candle to close below the low of the red candle to confirm the existence of bearish force. • Open a short position upon confirmation. • Place a stop-loss above the high of the red candle. #patterns#fibonacciacademy#trading

​​📉 Bearish Pattern - Shooting Star. How to recognise it? • There must be a preceding uptrend. • It looks like a flying meteor carrying a long tail. • The closing price is below or near the opening price, forming a tiny body. • The real body could be green or red. • It has no or little lower shadow. • The upper shadow is at least twice of the length of the real body. What is the psychology behind? • Similarly to Gravestone Doji, when the market opens, the bulls continuously push the price up during the session, resulting in a long upper shadow. • The bears fight strongly and conquer the bulls by dragging the price below or near the opening level, forming a little square body. • The longer the upper shadow, the more effective the bearish signal. It tells us that the bears are strong enough to conquer the bulls who once drove the price so high. How do we trade it? • Look for the Shooting Star at the top of an uptrend. • Wait for the next candle to close below the low of the Shooting Star to confirm the existence of bearish force. • Open a short position upon confirmation. • Place a stop-loss above the high of the Shooting Star. #patterns#fibonacciacademy#cryptocurrency
