And importantly, it's not so much about *predicting* "where the market will go next" as it is in *accepting* what the market has done so far,
and then placing a righteous STOP where the market has demonstrated that a true turn/
trend would hit. That's it! No magic! Measurement + numbers = {Entry/Exit/Stop}
And where did the TP (Profit-taker) part of the bracket go? With nods to a difference of opinion, let us pay tribute to the
mantra of trend-tappers:
"Let your winners run; cut your losers short."
I always thought that was a *hilariously* dumb, ignorant, ill-informed aphorism. Either you're *IN-vested* (I thought -- "Buy&Hold"ism), or you're a short-timer -- a
trader[!!] -- just looking to ride a quick up-or-down, and get out while the gettin' is good. I've had to have my eyes opened to a *marvelous*,
de-stressing, rules-based world of actually holding positions for an indeterminate length of time, with an exposure-reducing exit already pre-planned and ready for execution.
It's simple: with real trend
following, you first declare a trend (your MACD,etc Entry signal), and when that price movement violates your declared settings, you exit (following the received Exit signal). Long or short -- you don't care. Quickly or extended? You don't care. You are mechanistic, formulaic,
codable, detached, nearly-bored. And if that market goes for 7 days or 17 or 27? You're good. A turn will take you out, not a TP. You are letting any winners ride ride ride, while cutting those losers short. ("Like the ol' man sez!")
So! Three steps:
1) Tune the indicator (MACD under current view) to where its actions seem to match best with the asset/market you wish to trade.
2) Mark off entries and exits on the MACD.
3) Transpose those entries/exits to the asset/market chart (on the open, following the signal's closed candle), and start adding up results.
For the empirically-minded, there are 10,000 *obvious* ways to tighten this up, including ParabolicSARs, trailing stops, Bollinger-derived stops/reversals, dynamically-derived indicator parameters, yadda-yadda-yadda. This is just the least little nibble at a sizeable Fun With Numbers apple.

Tiny tiny tiny little nibble.
