Hi, I'm new to this site, I've been using Quantopian mostly. I had a question regarding syntax/how to approach my algorithm within the structure of QuantConnect. So what I'm trying to do is buy a stock, let's say "IBM" at open and keep track of that price. Then throughout the day sell all my shares in IBM if the current price rises by 30 cents or so, and buy as much as I can if the price drops by 20 cents or so. Then at the end of the day just sell all shares. Very simple but my implementation is throwing lots of errors :(
