Completely agree, and I'm well aware of this. The point that I was trying to make is not whether such a platform would make someone a winning trader. They would need a positive expectancy method to begin with to make money. But what I was saying is that it should improve the odds of making money. Or at least allow traders to have a smaller chance of blowing up while learning. To keep them in the game longer while they gain the skills to have a lasting trading edge. To that end, I think such a platform could make a lot of sense for undisciplined newbies and struggling traders.
Random uncertainty exists in every trade... likewise in casinos random uncertainty exists in every bet in every game.... a huge loss can be incurred at any given time on an isolated bet... however statistically over a large sample size they know they will always come out ahead...why? Because they have an edge... rules that put the probabilities in their favor.
So trading futures and only doing a one lot, how do you reduce this? As far as stop placement, that has to do with either being a scalper, day trader or swing trader, each has different stops. As far as risk, I can't tell low from high as all have that 50/50 attached to them, although most don't know how to change the 50/50 and really this takes years of testing. Too many test for profitable trading, as your experience kicks in, one might want to try other side of lowest losing percentages and what you have to do to get much much lower. Ninjatrader does have ATM in their Dom which will allow for set entries, different stops used and even volume stops, actually most I had developed several years previous, best to make your own so YOU can have what you want. Let's face it though, 2 items you mention, a beginning trader going to lose period if they did not take a few years first to study swings and price action, and best one starts with buy low and keep as long as you can. Buying low makes risk less and keeping as long as possible gives you ROR.
