Trader99, there seems to be some confusion here. I think you are confusing the "rules" with what guys like scalper joe are actually "recommending". You can trade all 15 lots when you go live. Why not, go for it. Nothing says you can't. What scalper joe is saying, and this is simply his opinion, is that you may not be able to control your swings well with 15 lots. I think it really depends on what you are trading. I mean 15 lots of the NQ is very easy and manageable, but 15 lots of crude oil not so much. I think you are taking joe's suggestions as facts when he is simply giving you his opinion. Most the guys here are simply trying to figure out how to optimize this and they are running through different scenarios. But you can trade 15 cars at a clip. Why not?
Maverick, by now you are well versed with the rules. The 150k Jr Trader account has a $600/day loss limit (when you factor in the weekly loss at 3k). Do you think it's realistic to trade 15 cars with a $600 stop? Even if you scaled into 15 lots, your stop is 3 ticks on a full position, as 4 ticks would auto stop you at minus $750.
So I don't think they will let you trade 15 lots when you go live. The rules of Jr Trader specify that you have to fill out a trading plan, which includes the max number of lots you will trade with to start, and that has to be accepted by the backer. And remember, as a Jr Trader, you cannot add to a loser, and you cannot add to a winner until you're up $1,000 in net P&L.
Even though the site may claim that you can trade within the same parameters in the live account as you did in the combine, my opinion is they are going to restrict the lot size until you build up the $4,500 cushion. As Ace posted earlier, you don't have to rush to get to Sr Trader, since there is no time limit, hence no need to "swing for the fences" once you're in the live account. It's a process that you work out with the backer, in terms of drawdown limits and lot size.
If Trader99 wants to scale in with 5 lots to start on the 150k Jr Trader account, my guess is that would be acceptable, and this is just my view, not TST or the backer.
The key question that Trader99 asked is what happens AFTER he makes Sr Trader. And from the TST site, it's unclear. And since there aren't any Sr Traders posting here, and no interviews of St Traders recently, we are speculating on various outcomes.
