Hi Sidner - that's remarkable, I've just been mulling this over with some notes in my personal journal. After thousands of trades all I can say is I believe there's no single right answer.
I'm a trend-follower using daily charts so not a million miles form your approach I hope.
Let's get this going. I would say there are basically four classes of entry: using an uptrend/upswing as an example -
1. buy in the pull-back - i.e. on a low and falling price. This might be triggered by a %age price fall or breaching a MA or closing below a MA etc. etc. But the key is to enter low, don't wait for confirmation.
2. enter after the pull-back has finished - i.e. buy on a low but rising price. This might be triggered by a %age rise or a MA situation again or breach of high of a swing low bar etc. The key is to wait for confirmation of buying interest to demonstrate the uptrend is still dominant.
3. buy on an off-chart technical signal - i.e. MACD cross or stochastic oscillator cross or whatever you prefer - irrespective of price, the indicator hopefully merely confirms buying pressure.
4. buy at new high - i.e. new all-time or recent high, or highest close in n days or breach of a prior swing high or breach of overhead resistance etc.
The actual signals, like hammers and outside key reversals and technical alarms I think don't really matter - its the trend that's doing the money-making work, not the entry signal. But where you enter on the trend is important, that's why I am coming to favour entry class 1. My risk isn't that the trend will fail, that's common to all entries, its that I will enter at a higher price than I could have got - I can live with that.
