I have been using these bots since September 10 and have found consistent losses.
For a while, I was a newby and was taken in by the regular 1-4% profit figure quoted in USD. But I realise now that the figure doesn't take into account the losses from deals that have gone into the red and that minimising losses is key.
One thing I have noticed is that deals opened using QFL are much more likely to return a profit than Trading View. TV cannot be trusted except with everything in place to minimise the loss.
Unfortunately, QFL trades are infrequent.
I was hoping to use this to make a living I could live off of, and thought I had found it. But I really don't think I can, and doubt it is possible.
