Let's talk a bit about the Diamond Setup #2 for instance: it's based on 1 chart only (I can't say which chart here, part of our little secret) and once price closes twice above/below the "key levels" it's the signal we need to take a short or long trade, depending on the time of the day we will use the "trend in play" to make a decision on which side the chances would be bigger, for instance, in a trend down day we'd look for a short entry.
When using the DS system we always have a t least 2 different approaches as to entering trades and using STOPs: Conservative X Aggressive.
Once decided which style fits better your OWN personality then use same approach on ALL trades you take, and as we know as traders, sometimes we will get stopped out and lose some money, that's just part of the game, no problem, the setups are designed to be profitable in the long run, from every 10 trades (or 100 trades if you prefer) we will be wrong on 20 to 30%, but on the 70 to 80% of the time we'll be right we make up the losses and soooooo much more!
As an example of a trade on ES (S&P500 e-minis), depending on your style you will use a STOP order from 6 (conservative) to max 10 ticks (aggressive).
So, you take the trade and market gives you say 6 points, or 24 ticks in profits, now you'd have to be wrong 4 times in a row, if trading the conservative style, to give all profits back, and I'm giving an example of 6 points only, but lately, with the higher volatility, it gives much more than that on a single trade.
One of the biggest problems I see in struggling traders is the "fear to pull the trigger" that keeps them away from being successful in this business...
Now tell me, would you be afraid to pull the trigger after a winner as in the example above knowing that the worse that can happen to your trade now is to lose 10 ticks?
Rules profit, make sure you use a system that fits your personality and leave opinions/emotions out of your trading.
Best of luck.
