A few days ago I published a Python Sanic backend and an Android app of a weekend project I did a few years ago. The project was simply directing people to a random cheapest return flights from where they are, set a budget and just press Go. It was written when async Python was beginning to mature. So I thought why not learn something new (FastAPI) and compare it with Sanic.

I have been playing the game since it launched, well over 3 months now. Have tried to play with RTX 2070 Super and RTX 3080. This blog post is more about the rationale on building a PC specifically to play the game and being able to enjoy it without blowing your pocket. Though to be honest, the latest and greatest will always be more enjoyable.
Talked more in details with specs on my last post.

As I said here and here, Microsoft Flight Simulator 2020 is beautiful. Been flying non-stop the past few months, to this day I’ve logged 229 hours of game time. Flying virtually made me remember moments and also an opportunity to learn something new. This blog post is about what you get in the game with combinations of CPU’s I’ve tested it on and RTX cards namely 2070 Super and 3080.

Lately I’ve been indulging myself in learning more about trading much more than cryptocurrency. During the last 2 weeks I jumped head first into Forex and Precious Metals. It’s different, volume is always high, unlike Bitcoin. Gained a new perspective, while other people might see as manipulation, I see how market maker moves as just another day at the office. Anyways, I learned how to automate some parts of the tradings, here’s what I experienced.

It has been known that the 3080 is a power hungry GPU while 3700X is supposedly a power efficient CPU with a TDP of 65W. Pairing the two should not be a problem powered by a Corsair RM 750W PSU, or is it? Here’s what happened to my rig.
Hardware Spec Before anything else, here is the spec I built:
AMD Ryzen 7 3700X Corsair H115i Pro AIO Watercooler AsRock X570 Taichi Motherboard 32GB HyperX Fury 3200MHz Palit Geforce RTX 3080 GamingPro OC Corsair RM750 80+ Gold The Problem The same 3080 was paired before with an Intel i7 8700K rig.

First of all, WHAT A FLIGHT SIM! In terms of graphics, I don’t think there’s anything close to rival. Leveraging Azure’s worldwide CDN to stream content is a brilliant feat, flight sim content being dynamic means improvements to the content will be delivered faster to us. Picture perfect graphics though comes with a hefty tax on our PC builds, this is next gen material.

My last post about my hackintosh is when I was still on Ryzen 3700X/X570 pair. It was overkill for my day to day work, instead I built a new PC just for the hackintosh and used the higher end pair for gaming. It was a great decision, introduced me to the microATX form factor.
For a work computer (trading and programming), a microATX board fits my use case. It’s small but it’s big enough to host all my peripherals.

For the longest time, I’ve been wanting to write a trading bot to leverage on TradingView’s alert system. For any indicator or strategy you use, you can set up alerts which will then send the notification to various destinations including a webhook. They have a strict 3 second must reply rule which is not trivial the first time I thought about it. Persistence and a lot of codes later wins though, found a way.

This is the second round of Bill Williams for me. This time it sticks and I built a system out of it. This is after paying a hefty tuition fee (losses), no more. As do with anything in life, the usual solution for complex problems is likely simple albeit far from easy.
How It Usually Starts As I said here, the most difficult concept for me to comprehend initially is Support & Resistance.

Anyone who trades using Technical Analysis knows what indicators are for sure. There are plenty of them available. As trading is becoming more serious instead of a hobby for me, I have an itch I need to scratch. I want to easily determine when to long or short given a set of indicators using predetermined (naive) assumptions of values.
Indicators Here’s a set of indicators I use for a strategy.
