Hundreds of people have received $150k accounts. The amount of money
nominally in the funded account isn't really relevant at all,
per se, and is a bit "artificial". What actually
matters is the scaling plan (i.e. maximum number of lots one's permitted to trade)
and that's explained here.
"Hundreds" have been funded however I'm not sure of the percentage of how many passed with 150k combines. Yes, what matters IS the scaling plan. This is what has been discussed extensively on this thread, yet so many still revert to the combine as the holy grail. To maximize the probability of utilizing the scaling plan, one must have enough EQUITY to take a draw during the scale up process. This is why if one is really serious about TST, then the only combines that make sense for building equity during the first 10 days in the live account are the 100k/150k, since on day 11 it's your equity that determines your draw. If your draw allowance is too small, then the probability of building equity (and hence utilizing the scaling plan is rendered moot).
From TST's rules regarding scaling: "Once you reach an increase in buying power or adjusted risk parameters, it will not decrease if you make a withdrawal or if your balance decreases."
The above statement is key. This is where a trader can optimize the value of a TST live account, since you can continue increasing your lot size
without increasing your equity cushion. In your own funded account, the exact
opposite is true. More lot size equals
more day trade margin. Since TST provides the day trade margin, scaling up size as you become profitable while keeping limited equity in the account is truly the definition of a "funded account."
The only area of uncertainty is whether or not they will allow a profitable trader to continue trading if they develop consistency and then fall below the "$0" starting balance. The current rules suggest they won't, however it's subjective to the decisions of the backer.
Comparing a 20 lot retail crude account with AMP vs. TST, it would require $20,000 in day trade capital with AMP, whereas TST is providing the capital. I stated this awhile back that a trader has to justify giving up the 20% haircut, and the only way is to continue scaling up
while using much less equity as required by a retail account.
