Here are my findings FWIW.
Intrigued by hearing a lot about him, I have been following Tom´s live trading for several months now. I do firmly believe that Tom, as a person, is a solid, honest, straightforward guy. He does not charge anything to any one for the knowledge he shares, he does not have anything to sell other than his book (which costs next to nothing).
YET, there is something that does not feel entirely right in all his trading and associated activities, and I cannot quite put my finger on it. Here are some thoughts:
* If you have strong edge like he seems to have, why would you put it up for grabs to more than 25,000 followers, for free, not counting all the people that just take his (simple) strategies off his website?? Hell, there are even several scammers selling signals on the back of his trading (which he is aware of) , so there is for sure a large degree of proliferation going on which can cause a threat to his system´s long term profitability. The risk is, if his results are real, that some institutional traders follow the strategy for huge size as well.
If an edge gets proliferated / known to so many competing market participants, surely it will cease to be an edge quite quickly . This is what I cannot get my head around. Why would you put your bread and butter at risk in such a way like he is doing???
Consider the fact - which I am sure you all know - that Renaissance Technologies and Jim Simons are mega secretive about their edge which gives them just shy of 51% winning percentage. Tom seems to have around 61% winning trades.
* This concern I have should be even more valid if we consider scalping / day trading to be a negative sum game, so why would you do that, i.e. giving complete insight, shouting your edge in detail from the rooftops??
If the algo´s / market makers sniff out what Tom (and by consequence thousands of followers and same system traders) are doing , (btw, most of his trade set-ups are very simple, precise and objective, based on H and L of specific "signal" bars, not vulnerable to subjective interpretations), they would start to trade against these weak hands and make money by picking off / squeezing all these short term traders and trades ... (by the way, I believe this MAY be what is slowly unfolding now, as Tom´s track record is slowly but steadily deteriorating, he recently had a rare loss month and his YTD bottom line is much less than what it used to be).
* Next point: if many of these CFD brokers (such as Tom´s) would see their client is consistently profitable, they would simply start copying the trades via a simple program and get exactly the same execution price and P&L on their copied trades. Hell, they could be themselves quietly selling the signals under a different name. That is what happens in the FX markets. Needless to say, the same signal/trade risks getting proliferated even more and would destroy the edge even quicker.
* I wonder if /why Tom has not yet asked these questions himself and what his response would be. He clearly is very smart so why never talk about these risks? Could it be he is counting on a huge execution wave of flow which he creates himself and rides in the first place? What would be the max capacity of trading size that could be executed before it starts to distort the strategy?
* For a private/self trader his stake size is very high (200 GBP per point). You can only trade that size, if you have unwavering solid confidence in your edge and system (and/or sit on a large pile of cash so you can´t be too stressed about losing a boatload per day). The psychology fluff (meditation) around his trading may be valid to some degree but is quite vague and imho OTT and can not in itself account for the successful track record (if it is real). Some of the trading greats admitted they were scared with every single trade they took, yet that did not keep them from performing very well and could even be the reason why they performed well... So this psychology bit about eliminating fear remains a question mark as to how much it contributes to his success.
* OTHER RED FLAGS: What I do find strange is that he does NOT show his live trading on screen, we never get to see the executions on his platform, account balance, trade blotter. How do we know if it is real money trading? How do we know he does execute at the entry and exit he says? He never seems to suffer from any slippage, yet many of his followers do. There is no third party track record at all. I have seen Tom being attacked and threatened quite aggressively by disappointed signal followers as is also shown higher in this thread.
Like some others have mentioned already, he swears by his off-shore small broker. A bit strange. Not sure what to think of it.
* BOTTOM LINE. So perhaps, as far as I can see, his only true edge is indeed adding to winning (short term) positions, not the system or entry/exit signals in itself which - given the large stake size- needs a decent amount of confidence. So imho it´s the "position sizing" component which is the driving factor, mixed with a "psychological" factor which is hard to quantify.
Food for thought: looking at his numbers of losing and winning trades as published by others above, imagine what the outcome would be IF HE WOULD NOT add to winners, his success rate would be closer to 50% or even below 50%.
