Stop hunting may or may not be a true market phenomenon. I do know that stops as well as buy/sell orders tend to be clustered in key S&R areas and when price enters those areas, it can trigger volatility in the direction of those orders. I will often use that zone as an opportunity for order fill at the extreme levels depending on my targeted outcome.
Since you posted that chart with the trend lines, price has broken the lower line and is currently in a small retrace. Perhaps it will resume the retrace it has been in this morning but 1.20 most likely has enough institutional interest to keep trading in that zone for a bit. I don't trade for 5-10 pips on 5 and 1 minute charts. Too much noise. That said, trend lines can provide some guidance but I would not use them by themselves.
Trading small is relative to the account size. I don't over leverage my account. That's different.
Plot a 5 and 20 EMA on a chart. Then add a 5,3,3 regular Stochastic.
When the 5 crosses the 20 down, wait for the Stoch to also cross downward over its D (average) if over 50%. The higher the better. That is a sell.
When the 5 crosses the 20 up, wait for the Stoch to also cross up from under 50%. The lower the better. That is a buy.
If the 5 stays above the 20, you can add to your position whenever the Stoch crosses upward from below 50%. The first and second cycle are usually good and then the processes weakens. True in the reverse for sell trends as well.
If, on any Stochastic cycle the EMAs cross, then it's not a trade. Too much chop. The best case (for a buy) is a deep cycle down in the Stochastic and for the 5 to remain above the 20. That will show that short price action was strong enough to create cycle depth but not strong enough or long enough to weaken the short term average.
Play with this on an hourly chart and you will see how cycles of momentum can be used to determine entries and exit. This simple method is VERY basic but it's a good tool for recognizing price rhythm. It's also not perfect, as nothing is. But it will also show you when conditions are ideal and when they are not.
Place a vertical line on the chart every time the exact conditions were met. Find as many as you can. Count up the wins vs the losses (price went in the direction of the entry).
Compare what the factors of the losers were. Flat trend? Weak trend? Choppy? News?
Compare things in common with the winners?
On an hourly chart, how many pips on average did each winner produce if you exited at the first reversal of the next Stochastic cycle? Best? Worst? This gives you an idea how to set your profit expectations.
This is how you build a rule base.
