Estratégia Simples de Trailing Stop
Este exemplo demonstra como gerenciar uma posição aberta com um trailing stop usando a API de alto nível do StockSharp.
Visão geral
- Abre uma única posição comprada após receber a primeira vela concluída.
- Ativa a proteção de posição com um trailing stop.
- O preço do stop segue o preço atual a uma distância fixa.
Parâmetros
TrailPoints – distância em pontos de preço usada para o trailing do stop.
CandleType – tipo de velas processadas pela estratégia.
Lógica
- Ao iniciar, a estratégia se inscreve em velas e ativa
StartProtection com trailing.
- Após a primeira vela concluída, a estratégia compra a preço de mercado.
- Quando o preço se move a favor da posição, o nível do stop é movido para manter a distância definida por
TrailPoints.
- Se o preço reverter e tocar o trailing stop, a posição é fechada automaticamente.
A estratégia é simplificada e tem como objetivo mostrar o uso básico do trailing stop.
