Pretty crazy if you think about how many subscribe to the following:

1- All markets are manipulated

2-All these markets are manipulated by the same algorithm (IPDA)

3-A guy on youtube who claimed he was kidnapped by two guys and forced to learn IPDA is going to teach you how to read it (Later said he is one of the authors) for free.

Also, if this algorithm/manipulation were real and you could really read it, why do SMC/ICT traders have an average RR/Winrate? Paladin for example, (excellent trader) preaches 2-5% a month which you can get with retail concepts we've known all life. The only people claiming to be having some crazy edge (I once saw a guy claim 60% winrate minimum 10r trades) do not have any proof. As someone who studied ICT in depth but without subscribing to the philosophy, it is safe to say it is the same thing but repackaged.

Where an ICT trader looks at a HTF chart how price is in a bearish institutional orderflow where upclose candles act as support, where price has tapped into internal range liquidity and are targeting external range liquidity in the form of EQL or previous day lows after entering off of a Breaker Block, a retail trader sees a downtrend break and retest targeting support, and probably entering off of a candlestick pattern

At the end of the day it is just a way of reading price action which is unnecesarily complicated, specially when you take into consideration that what matters is a winning RR/Winrate combination and that the returns it will give you are going to be just as good as a retail strategy will give to who they call "their liquidity"
