quicky

A command line program to allow day trader to quickly place a limit order instead of convenient but more fee of market order.

Usually we don't have to quickly place a market order in order to ensure we get into the position. But if we take advantage of volatility of the price, eventually we will have a position with limit order.

Some of exchanges have convenient UI to allow traders to quickly place a limit/market order, some don't. Anyway, even with availability of such convenient UI, traders still need to precisely get the nearest price (mostly a tick step away from the current trade price up or down) by hovering the mouse cursor, or fallback to use normal order form but time needed in order to find the price, and fill it into the form.

Thus quicky will help speed things up.

---

It takes advantage of ByBit exchange because limit order has a rebate fee of -0.025% compared to market order of 0.075%. Thus placing a limit order will minimize the fee, and maximize profit at the end. Thus quicky is specifically implemented to work with ByBit exchange.

Setup

• Create API on Bybit exchange bot for mainnet, and testnet, and setup permission accordingly to only what is needed for your bot
• Define the following environment variables (on Linux via ~/.bash_aliases, etc), and make sure you source the file
  • BYBIT_API_KEY - API key for mainnet
  • BYBIT_API_SECRET - API secret for mainnet
  • BYBIT_TESTNET_API_KEY - API key for testnet
  • BYBIT_TESTNET_API_SECRET - API secret for testnet
• cargo build --release - Better to build and use release build, minimize time as much as possible apart from HTTP request we would be definitely doing
• cargo run --release -- -s XRPUSD -q 1 --testnet or locate quicky binary and execute it like quicky -s XRPUSD -q 1 --testnet
