Resumo

Esta estratégia combina múltiplos indicadores técnicos, incluindo SAR parabólico, média móvel exponencial tripla (TEMA), média móvel exponencial (EMA), índice de força relativa (RSI), volume no saldo (OBV), etc., para identificar sinais de reversão de preços de ações, com filtragem de tendência adicional e stop loss para gerar sinais de compra e venda.

Estratégia lógica

A estratégia usa o SAR Parabólico como o principal indicador para sinais de reversão de preços. O SAR aparece acima do preço em estado de alta e abaixo do preço em estado de baixa. Quando o SAR rompe para cima a partir de abaixo do preço, um sinal de venda é gerado. Quando o SAR rompe para baixo a partir de acima do preço, um sinal de compra é acionado.

Para filtrar sinais falsos, a estratégia usa cruzes TEMA ou EMA como sinais de confirmação. Somente quando o sinal SAR aparece junto com os cruzes TEMA ((linha rápida cruza acima da linha lenta) ou EMA ((linha rápida cruza acima da linha lenta), um sinal de compra será gerado. Da mesma forma, apenas o sinal SAR mais o cruzeiro TEMA ((linha rápida cruza abaixo da linha lenta) ou EMA ((linha rápida cruza abaixo da linha lenta) podem desencadear sinais de venda.

A estratégia prevê também um indicador RSI e um indicador OBV como sinais de confirmação alternativos.

Além disso, o gráfico do indicador Triple EMA é exibido para oferecer uma visão clara da tendência dos preços.

Um quadro de resumo dos valores de múltiplos indicadores é igualmente apresentado na parte inferior do gráfico para uma rápida visão geral.

Forças

Ao combinar SAR, EMA/TEMA, RSI, OBV e outros indicadores, a estratégia pode efetivamente detectar sinais de reversão de preços e evitar falhas.

A visualização gráfica rica de múltiplos indicadores permite uma observação e análise abrangentes do mercado.

As regras da lógica de negociação são claras e os parâmetros configuráveis, o que torna a estratégia adaptável a diferentes instrumentos de negociação.

Riscos

A estratégia depende de cruzamento de indicadores para gerar sinais. Configurações incorretas de parâmetros de indicadores podem produzir sinais ruidosos excessivos. Parâmetros de indicadores precisam ser ajustados com base em diferentes características de instrumentos de negociação.

Em mercados de variação e de variação lateral, o indicador SAR pode gerar sinais falsos frequentes.

A falha da estratégia pode também resultar de uma escolha inadequada dos instrumentos de negociação.

Orientações de otimização

A estratégia pode ser reforçada pelos seguintes aspectos:

  1. Otimizar parâmetros SAR para reduzir sinais ruidosos
  2. Otimizar os parâmetros da média móvel para um melhor julgamento da tendência
  3. Tente diferentes indicadores de confirmação como RSI e OBV
  4. Adicionar mais indicadores auxiliares para análise de quadros de tempo múltiplos
  5. Otimizar os mecanismos de stop loss para limitar as perdas por transação

Conclusão

A estratégia de negociação parabólica de paragem e reserva de múltiplos indicadores integra vários indicadores técnicos comumente usados para formar sinais de compra e venda sistemáticos. Pode identificar efetivamente pontos de reversão de preço. Os parâmetros configuráveis facilitam a otimização para diferentes instrumentos de negociação. Os traders quant experientes podem tirar proveito desta estratégia. No entanto, a regulação de parâmetros baseada em características específicas do instrumento é uma obrigação. Além disso, os instrumentos de tendência devem ser selecionados para evitar sinais ruidosos excessivos.

//
// PSAR + EMA + TEMA combines Parabolic PSAR plus EMA and TEMA trendlines.
//      - EMA and TEMA crossovers have an up or down triangle to indicate direction of cross.  Please note
//          that because these are Moving Averages (MAs), the triangle may not exactly line up with the crossover.
//      - Added MESA Adaptive Moving Average (eMAMA).  Crossovers of the fast and slow eMAMA may be used instead of 
// 			EMA or TEMA.
//		- Added third EMA line.  May be used to filter entries.  For example, set the additional EMA to 200.  Buy signals
//			wil only be sent if the price is greater than the additional EMA.
//		- Added RSI and OBV as alternative PSAR confirmations.
//
// "Traffic Light" table: summarizes PSAR, RSI, SRSI, TEMA, EMA, eMAMA, MACD, OBV, and CMF indicators in a table.  
//  This is intended as a quick "heads up", not to replace the indicators themselves.  
//      - Arrows indicate direction of change since the last bar.
//      - Moving average indicators are indicated as green if the fast MA > slow MA and fast [T]EMA is increasing, red otherwise.  
//          [T]EMA will be yellow if fast MA has increased over the last 2 periods but fast MA < slow MA.  
//      - PSAR is as green if the PSAR is increasing, red if it is decreasing.
//      - RSI is indicated as green if RSI < oversold, red if RSI > overbought, yellow otherwise.  
//      - SRSI is indicated as green K < oversold, and red if K > overbought.  If oversold < K < overbought,
//          green if K > D and red if K < D.
//      - MACD, OBV and CMF are green if bullish, red if bearish.
//
//
//  Suggestions for use:
//      - Use fast EMA crossing above slow EMA as a confirmation for PSAR signals.
//      - TEMA or eMAMA can also be used for confirmation signals insead.
//      - Instead of using a moving average (EMA, TEMA, etc) for confirmation, you may use RSI or OBV.
//      - The "traffic light" table is intended as a "heads up" to call your attention to other indicators
//          you may want to check.  I suggest Cipher B/VMC Cipher_B, Neglected Volume, and/or CM_Ult_MacD_MTF
//          as useful comparions.
//
// Please don't rely solely on the table.  It is intended to alert you to look more closely at a plot, not to 
//    provide all the information you need to enter or exit a position.  I find the table to be a nice companion 
//    to VMC Cipher_B, which can be overwhelming in its complexity.
