I'm not sure wether automatic trading is more efficient or not. I'm building a bot because of my engineering background: I love automating processes and wanted to try my hand at cryptocyrrencies. So trading bot is the perfect project!

My bot is capable of buying or selling at anytime. However, I need ideias for strategies on when to buy/sell and for how much, so that I can make a profit. My Intention is to program the bot to look for those profit opportunities and take the according action.

My doubt lies on the economics of deciding when to buy/sell!

Greetings, everybody.

I'm starting q bitcoin trading bot using a popular platform in my country that provides APIs for transactions.

I have all the technical aspects of the project functioning, but am struggling with the trading strategies.

Here's how it works:
Every 15 seconds the bot gathers BTC prices and checks for buy/sell opportunities.
Every 30 minutes the bot sends me a balance report on Telegram.

The "checks for buy/sell opportunities" is the part I'm struggling with. Do you guys have any recommendations of strategies or source that I could use?

Note: The platform charges a 0.7% fee on any buy or sell transaction
