Support/Resistance

just want (curious) to know what is your "LOGIC" you use and its pay you high return with limit risk.

Please, I don't want a comment like putting me down or discourage. thanks

my logic is ...I dont want to lose money.

But I think you mean what tools we use as far as technical analysis goes, I use candle charts, and moving average as well as running standard deviation calculation to get an idea of what is statistically likely to be the close price, and I look at my interpretation of trend, or how strong the market is reacting at some levels, then I make a calculated guess on what would be the most probable outcome either close below open or close above open, then I make a trade, assuming I am wrong (so I have calculated risk parameters)

Without wanting to come across as being smarmy or cliche, exit logic can actually have more of an impact on your trading than the Entry.

Assumption of trend reversals is the bulk of what you will read and hear about in the Halls at FF in the active trade section and its threads.

Positions without merit, stop loss and take profit points that have no logical market sense, gamble trades by gambling traders is what this all boils down to.

Understanding the triggering logic of any indicator/system and applying it to the fractal patterns of the multiplicity of time frames will inevitably only give you an idea of how to play winning trades. This doesn't account for what happens, when the proverbial shit hits the fan and the trade goes wildly against you. In these times, it really doesn't matter so much as to where you took your entry as much as self account preservation should actually kick in. This is the logic that you should actually be focused on.

Besides that, venturing through the various trade systems, there are a few good ones to view that will give an idea of both, when to take entry, when to take exit and what happens when the market goes against.

Simple indicator logic...well, this you can find at babypips, freestockcharts.com, google and wiki.

Trend, retrace, momentum, AND always sound MM.

I firmly believe in "The Trend Is your friend". i make sure that i trade with the trend and i get in as early as possible (meaning, for a trend to change at my trading time frame.... it needs to change first on the time frames less than it.)

I make use of Moving averages (for entry and trail), RSI & Trend indicator (just to know the current trend on all the other time frames). i then have a rule that says i rather let the trade hit my initial stop loss than closing a trade with less than 1:1 (Reward to Risk Ratio). My Standard R:R is 3:1

Reason for entrance: TREND = Simply identified by looking @ EMA (12) ONLY!
The trick is how to manage your positions correctly.
