Estratégia SAR RSI MTS
Visão geral
A Estratégia SAR RSI MTS é uma tradução direta do consultor especialista original do MetaTrader 5 "SAR RSI MTS" para a API de alto nível do StockSharp. O sistema segue a direção do indicador Parabolic SAR e confirma as entradas com o Índice de Força Relativa (RSI). Funciona apenas em velas completas (período padrão de 1 hora) e respeita um limite configurável no tamanho líquido da posição.
Indicadores e dados
- Parabolic SAR (
Acceleration = SarStep, AccelerationStep = SarStep, AccelerationMax = SarMax).
- Índice de Força Relativa com período personalizável e nível neutro (padrão 50).
- Velas fornecidas por
CandleType, que assume por padrão dados de período horário.
Internamente a estratégia calcula um valor de pip a partir dos metadados do instrumento. Se o símbolo tiver 3 ou 5 casas decimais, multiplica o passo de preço por 10, correspondendo ao tratamento de pips do programa MQL original.
Lógica de entrada
Uma nova operação é avaliada no fechamento de cada vela concluída após ambos os indicadores produzirem valores válidos:
Configuração comprada
- O valor do Parabolic SAR da barra anterior está abaixo do fechamento atual e o SAR atual aumentou em relação ao valor anterior.
- O RSI está acima do limiar neutro e está subindo em comparação com a leitura anterior.
- Se a conta já estiver líquida vendida, a estratégia primeiro compra volume suficiente para inverter a posição e então abre uma nova posição comprada dimensionada pelo parâmetro
Volume, respeitando o limite MaxPosition.
Configuração vendida
- O valor anterior do Parabolic SAR está acima do fechamento atual e o SAR atual diminuiu.
- O RSI está abaixo do limiar neutro e está caindo em comparação com o valor anterior.
- A exposição comprada existente é zerada antes de estabelecer a nova posição vendida. Posições vendidas adicionais são permitidas até que a posição absoluta atinja
MaxPosition.
Todas as comparações usam a precisão do instrumento para que os testes de igualdade correspondam ao helper CompareDoubles original do MQL.
Saída e gestão de risco
Os controles de risco são avaliados antes de verificar novas entradas em cada vela concluída:
- Stop-loss fixo em pips convertidos em unidades de preço e aplicado ao preço médio de entrada da posição líquida atual.
- Take-profit fixo em pips, tratado simetricamente ao stop-loss.
- Trailing stop que fica ativo somente após o lucro não realizado exceder
TrailingStop + TrailingStep. O stop é movido em passos discretos, imitando a rotina "Trailing" da estratégia MQL.
- Se nenhum dos itens acima se aplicar, o estado do trailing é reiniciado sempre que a posição se tornar plana.
Todas as saídas fecham a posição líquida inteira (comprada ou vendida). Quando uma regra de proteção é acionada, a estratégia ignora a avaliação de sinais para a mesma barra, espelhando o comportamento de ordens stop do lado do broker na implementação original.
Parâmetros
| Parâmetro |
Descrição |
StopLossPips |
Distância do stop-loss expressa em pips. Um valor de 0 desabilita o stop de proteção. |
TakeProfitPips |
Distância do take-profit em pips. Desabilitado quando definido como 0. |
TrailingStopPips |
Distância do trailing stop. Desabilitado quando definido como 0. |
TrailingStepPips |
Melhoria mínima de preço necessária antes de avançar o trailing stop. |
SarStep |
Passo de aceleração para Parabolic SAR; também usado como fator de aceleração inicial. |
SarMax |
Fator de aceleração máximo para Parabolic SAR. |
RsiPeriod |
Período de lookback para o indicador RSI. |
RsiNeutralLevel |
Limiar RSI que separa a tendência de alta e de baixa (padrão 50). |
CandleType |
Assinatura de velas usada para cálculos (padrão 1 hora). |
MaxPosition |
Posição líquida absoluta máxima permitida pela estratégia. |
Notas adicionais
- A configuração padrão reproduz as entradas originais do EA: stop de 10 pips, alvo de 40 pips, trailing stop de 15/5 pips, Parabolic SAR
0.05/0.5 e período RSI 14.
- O volume é controlado pela propriedade base
Strategy.Volume. O dimensionamento de posição respeita MaxPosition e lida automaticamente com reversões.
- As ligações de indicadores e o roteamento de ordens dependem inteiramente da API de alto nível do StockSharp sem acesso manual a séries, garantindo conformidade com as diretrizes do projeto.
