Yesterday, while running a quantitative strategy, I encountered a ridiculous problem. META's intraday reversal opportunity looked promising, and pre-positioning was reasonable, but the position inexplicably ballooned to over $2 million. Far beyond our established risk control limit. After entering the position (at that blue dot), backtest data showed unrealized losses much more exaggerated than expected, which caused panic in the entire team, and we immediately activated emergency troubleshooting mode.

After messing around for a while, we finally found the culprit—the robot was dumb and completely failed to recognize the previously placed long orders, misjudging them as a flat position. At that moment, I almost felt my heart jump out of my chest. But this crash also gave me a clear realization: predicting the market direction is always the top priority. As long as the main trend is correct, a few bugs here and there won't be fatal. Our account later recovered from a loss of over $20,000 to a profit of more than $2,000.

Of course, the ideal state is to completely eliminate bugs. Next time, we will improve the process to prevent such issues from happening again.

A position of $2 million expanding, haha, this is the fun of quant trading, so exciting The bot is acting up and can't recognize long positions. Such basic mistakes definitely teach a lesson, but as long as we recover, it's not a loss The main direction is correct; everything else is minor. There's some truth in that statement, well said Risk control still needs to be thoroughly improved at the code level. Relying on manual inspection will only lead to another round sooner or later From losing 20,000 to making 2,000, at least we're still alive, right?

Over 2 million directly inflated, this bot is really amazing. Luckily, the direction didn't reverse.

Haha, robots really can cause harm. My bot has also had such glitches. $2 million inflation... that’s really scary. Luckily, it was turned around in the end. As long as the direction is right, there is hope. This is the truth.

Oops, playing with a position of 2 million USD like this is really awesome. The robot took the blame directly this time. If you ask me, as long as the direction is correct, everything else is just details. Turning it around means winning. It's indeed outrageous that the robot doesn't recognize long positions. We need to be cautious next time. Let's just consider this as paying tuition. At least I didn't get liquidated. By the way, can it really be fixed? From loss to profit, it's also a rescue, but it's really exhausting.
