The market only goes in the direction that my analysis anticipates it will go, about 50% of the time. Combined with a pesky spread and commissions, and it starts to look bleak.
Bascially lack of 'edge'
I've traded just about every instrument under the sun. Demo and live.
At the moment i'm mainly trading NQ.
1) You need a plan for EACH TIME PERIOD in the market day.......930-10:00est behaves differently than 10est-1200p and differently from 130-330pm. Targets, stops, reasons for entry, reasons to avoid entry, etc are all different depending on time period. 930-1000 is best traded on 89 tick or 1 min time frames IMO. 10am-12pm is best on 3-5 min TF's, and 130-330 best on 15min - 60 min, in my own experience.
2) Market behaves differently depending if the hourly / daily is uptrending, downtrending, pulling back from an uptrend, pulling up from a downtrend, ranging, reversing, etc. Price has a distinct feel to how it moves depending on if it trending or ranging in regards to high time frame charts. You need to study this.
3) Volatility. Watch what makes price increase or decrease in volatility. A market that goes up 6 days in a row will have contracted volatility b/c price is becoming more in equilibrium. A market that shows a temporary reversal, and begins downtrending will have expanded volatility. Each of these market contexts will have VASTLY different opportunity and your system must be modified to trade this. This is why trading just chart patterns is not an edge by itself.
4) Indicators. A market like the ES is mean reverting. Having indicators like an oscillator and a moving average (range or trending market) serve a purpose. That purpose is usually when NOT to take certain trades that your eye won't see with just a plain chart. This will increase your win %.
5) Know when NOT to trade (similar to part4). If I suspect a day is going to be unfavorable for my trading system, Ill normallly get confirmation of this within the first 15-20 mins of the day. With that being said, I'll modify my plan to walk away after getting a MUCH SMALLER PROFIT TARGET than usual. Sometimes, thats just 1 trade and 1 ES point.
There's much more, but those are just some helpful ideas to get u moving in the right direction.
