Spare RPi? You Have A Currency Trading Platform

While Bitcoin and other altcoins are all the rage these days, there is still a lot of activity in the traditional currency exchanges. Believe it or not, there’s money to be made there as well, although it rarely makes fanciful news stories like cryptocurrency has been. Traditional currency trading can be done similar to picking stocks, but if you’d rather automate your particular trading algorithm you can set up a Raspberry Pi to make money by trading money.

This particular project by [dmitry] trades currency on the Forex exchange using an already-existing currency trading software package called MetaTrader. This isn’t an ARM-compatible software suite though, so some auxiliary programs (Wine and ExaGear Desktop) need to be installed to get it working properly. From there, its easy enough to start trading in government-backed currency while reaping all of the low-power-usage benefits that the Pi offers.

[dmitry] does note that you can easily use MetaTrader on a standard laptop, but you might be tempted to go against your trading algorithms and even then you won’t be reaping the power benefits of the ARM processor. We don’t see too many traditional currency or stock trading tips around here, but don’t forget that it’s still possible to mine some types of cryptocurrency even if BitCoin is out of reach of most now.

Hackaday Prize Entry: ForEx Display Is A Well Executed Hack

[Stefan] works in a place where knowing the exact state of the foreign-exchange market is important to the money making schemes of the operation. Checking an app or a website was too slow and broke him out of his workflow. OS desktop widgets have more or less departed this earth for the moment. The only solution then, was to build a widget for his actual desk.

The brains of the device is a ESP8266 board, some peripherals and a small backlit TFT display. The device can run off battery or from a wall wart. [Stefan] even added some nice features not typically found in hacks like this, such as a photocell that detects the light level and dims the screen accordingly.

The software uses an interesting approach to get the latest times and timezones. Rather than use a chart or service made for the task, he uses an open weather API to do the task. Pretty clever.

The case is 3D printed and sanded. To get the nice finish shown in the picture [Stefan] spray-painted the case afterwards. All put together the device looks great and gives him the desktop widget he desired.
