lets say the signals worked a high % of the time . As new subscribers come online and old winning subscribers leveraged up from their winnings , the volume coming in ever time the signal came up would crash the servers at the exchange at some point . So the systems only work in back testing .

@forgiven,

Capacity decay is real but it depends on the product. ES does 1.5-2M contracts/day -- a few hundred subscribers watching the same level isn't moving that needle. Try that on SI or RTY where book depth is garbage and you'll eat your own fills alive. Different problem entirely.

That said, capacity isn't usually what kills these things. Overfitting is. You can make any backtest look incredible if you optimize enough parameters against historical data. Lopez de Prado has written extensively about this -- most backtested strategies that look amazing are just fitting noise.

Re: BWT's "probability statistics" on Core Levels -- what probability? Over how many trades? What's the max drawdown look like? Without that info it's just marketing.

And your point about subscription revenue vs. trading revenue is the elephant in the room. If someone's actually printing money trading, why bother running a $199/month chat room? Unless the chat room IS the money printer.

You've got NinjaTrader with order flow and charting tools that adapt tick by tick on ES and YM. I'd take that over any static level generator.

Have a good weekend!

@forgiven,

Fair enough -- the ignore list is there if you'd rather not see my posts. No hard feelings.

That said, the capacity decay point you raised earlier was solid. When a signal service scales past a certain subscriber count on instruments like ES or YM, the edge erodes fast. That's worth discussing regardless of who's bringing it up.
