I did something similar-ish (or maybe the opposite!? 🙂 ) for a trial month recently (on Demo) … I allowed the Auto-Systems to take the trade as normal, but then as soon as I got chance I dived in and assessed the probability of any profit / loss continuing (taking into account Market structure) and either exited the trade or continued to monitor.
I set an Alert within the IG Platform to send me a Notification (pushed to my mobile phone) whenever a trade was opened and I then opened the IG App open on my phone.
It was a very successful month … giving me over £5k in Demo profit!
It has to be said though the best set of trades and a pleasant surprise was when I went on a walk in the hills and was out of signal / network. When I returned back into signal I was £846 in profit!! 🙂
