Sma Pullback Atr Exits

Regras de negociação

Com velas encerradas, SMA de fechamentos e ATR de Wilder formados, comprar se fechamento < SMA rápida e rápida > lenta; vender se fechamento > rápida e rápida < lenta. Igualdades não geram entrada. Volume apenas sem posição, aguardando ordens pendentes. Fixar SL = ATR×AtrMultiplierSl e TP = ATR×AtrMultiplierTp no sinal. Proteção local nativa ancora distâncias na execução real e observa bid/ask. ATR posterior não move níveis. Encerrar todo saldo pela proteção, sem reversão por sinal contrário.

Parâmetros

Parâmetro Padrão
CandleType TimeSpan.FromMinutes(30).TimeFrame()
FastSmaLength 8
SlowSmaLength 30
AtrLength 14
AtrMultiplierSl 1.2
AtrMultiplierTp 2

Verificação

Ambas as linguagens são verificadas com BTC/TON incluído, fórmulas independentes, direção/tamanho das ordens, execuções, posições e saídas. Dados datados de preços/fatores e calendário verificam mecânica; OHLC/volumes deslocados não são história plurianual. Dois grupos, TopN=1 e SMA=2 são perfis pequenos explícitos. Janelas longas e valores originais são verificados separadamente. Sem promessa de rentabilidade.
