Quote from XEC10:
...
We look at a price chart and within our timescale of interest, we decide where price may go to as a possible target, and where it may go to as a possible stop, or whether price may not move much at all. We use our experience of interpreting charts, observed S/R levels, market indices, futures, news and conclude the likely future direction and extent of a price move.
Some traders have more trading experience and access to information than others, which can be used to narrow down the uncertainty of price movement. The lack of precise information means that we consider a range of possible outcomes of a trade and we try to manage the uncertainty and risk:reward by thinking in terms of probabilities, of our target being hit before the stop:
Expected_gain = Expected_win x Probabilty_of_win - Expected_loss x Probability_of_loss
We try to choose the entry, target and stop so that the expected gain is positive and that the risk:reward is sufficient:
RR = Expected_win / Expected_loss.
Each trade is unique and won't be repeated, but we take the trade on the understanding that if the trade could be repeated with our choosen entry, target and stop under the same conditions, except for those aspects that are uncertain, then the odds are in our favor the we would gain in the long run for that particular trade.
