It's all math, ..
1) you need enough of a initial balance to weather price variance.
Let's say you saved 10k.. that 10k took a few months to save.
2) ES is 50 per point,.. what's the usual range been recently.. under 10 points per session.
10 points = 500 bucks.. or 5% of your balance. Let's say your able to grab half that or 2.5%.. how many points can you risk to make 2.5%.. 1%?.. or 2 points...
If you can only risk 2 points and daily ATR dwindled to 10 .. you would end up playing the edges of the ATR.. if you play in the middle most likely you get chopped up.
If the long term trend filter indicates up.. you end up waiting for the bottom of ATR, with a 2 point stop. Only take longs with 2 point stop.
At the bottom of ATR look for breaks in vector direction, like trendlines or EMA crossovers.
To make it even more probable.. wait for fast market days,.. like FOMC/Econ reports. Key is to never go against you intraday trend filter.

There are like 12 videos there.. .wmv file .. full download is needed. Good to watch price action and how the ticks fly.
So it's all math... if you loose 1 percent on each decision,.. realistically if you kept banging away on high probable days.. you can make 20 points.. 10 stop outs you loose 1k.. play high probable days to make 20 points.
Library videos are all demo videos.. still valid to see how transparent price action is on news days.
You would need 20 high probable days to double your account. There are probably about that many in a whole year. Trade only those days,.. and work or study the rest.
If your truely crazy.. reduce your capital to 10 decisions. Meaning you risk 1k per decision. Or 10 contracts with (500 intraday margin)..2 points on 10 contracts is 1k.. you can make 10 decisions on a high probable day before blowout. 10 contracts 20 points.. 200 points.. or 10k.. account doubles each probable day.
