Ao minuto: EUA atacam Irão. MNE iraniano diz que país "reserva todas as opções" para se defender

indicador fiável, terá de ser observada tendo sempre em conta o padrão dos preços e outros indicadores e até os índices.

Serve mais como suporte da tendência e não como base de um sistema mecânico de negociação

Eu por mim, não sei porquê mas uso sempre uma média móvel de 20 dias, mas simples

ainda fiz mais um teset. Abrir posições se a vela não toca a EMA, fechar se tocar na mesma e só abrir novamente quando passa a zona de transição. E os resultados continuam a não ser brilhantes.

Camisa Roxa, fui fazer o teste no meta... e essa forma simplista tem resultados bastante fraquinhos... testei na QQQ e na nokia, e fiz os testes incluindo os períodos de transição e depois sem os incluir, obrigando a entradas quando as velas não tocam os valores da EMA.

.... muito engraçado, mas sem grande aplicação per si. O equivalente a outra qq mm, digo eu...

Everyone's looking for the perfect market indicator. The search will be fruitless,
however, as there is not one. However, there is a powerful indicator that is easy to
use, and most anyone can access. It's the 20 day exponential moving average (or EMA).
While it's not as complex as stochastics or ADX, it's a very effective tool at
spotting the beginning and ends of trends.

Often overlooked, the 20 day exponential moving average is simply an average of the
previous 20 closing prices, with more weight given to the most recent closes (as
opposed to a simple moving average, which weights all the closes equally). Although
there's no magical reason why a 20 day average would be more effective than say a 10
or 25 day average, the charts tell the tale.

In the chart below of the QQQ, the red line is the 20 day EMA. Areas where the 20 day
line has been a critical level are circled. When the stock crosses over or under the
20 day line, that often sets a new trend, as it did in the areas marked "Crossovers".
Typically you want to see two closes on the other side of the 20 day EMA to confirm
the new trend. Similarly, a gap over or under the 20 day line is an indication of an
even stronger trend. The bullish October gap set into motion one of the strongest two
month rallies ever. Finally, the 20 day line acted as support in the middle of that
rally. While we saw prices right at the line then, we never saw two closes under it,
confirming and continuing the bull trend.

This is particularly important as of today since we recently made a bearish gap under
the 20 day line. Even with today's strength, the QQQ's will still need to cross the
25.86 level and stay there for two closes to suggest an end of the recent bear trend.
If the 20 day line acts as resistance instead (sending the QQQ's downward again),
that actually suggests that we are in the middle of a fairly strong downturn.

And it's not just the QQQ's. The 20 day EMA line can be applied to all of the indices
and all stocks with equal effectiveness. While there are obviously exceptions to the
rule, using this simple indicator can really help you spot the big trends.
