I am new to QuantConnect and experimenting a little bit. I have a very simple algorithm, which attempts to keep the amount of dollars invested per symbol constant. With stock prices fluctuating, it is expected to trade a few shares pretty much every day. When running the algorithm with just one stock, it does exactly that. However, when running it with two or more stocks, it stops trading at some point (with 2 stocks on 2015/10/24). The more stocks I add, the earlier it will stop trading.

I have a hard time understanding what's going on here. Am I hitting some limitation? Are there any workarounds?

Any comments highly appreciated!
