Like on the order execution front, I've noticed some serious lag. We're talking a few minutes during peak trading times. This isn't cool, because it ends up causing slippage, which means my orders aren't being filled at the price I want. It's super annoying, especially when you're trying to make a quick move. Now, about the trading costs, they were through the roof. The commissions were higher than what I've seen on other platforms. Combined with the wider spreads, it really started eating into my profits. It's like you're running uphill, you know?
