To be fair, Iv seen it done in front of me, While i was training, my mentor turned £15 on a Monday to £1600 by Friday on a live account, while he was trying answer the question about does account size matter. I was arguing it did and mentor said Accuracy and consistency is far more important, and to be honest we had days were i would be up in the morning at 6am and sit with him till 4-5pm with not a single entry so Accuracy is a must. Its all about knowledge. Many people talk the talk but not walk the walk. If your looking to invest with someone sit with them and tell them to do it.
