La estrategia de trasplante se basa en una estrategia de lenguaje simple:

TR:=MAX(MAX((H-L),ABS(REF(C,1)-H)),ABS(REF(C,1)-L));
ATR:=EMA(TR,LENGTH2);

MIDLINE^^EMA((H + L + C)/3,LENGTH1);
UPBAND^^MIDLINE + N*ATR;
DOWNBAND^^MIDLINE - N*ATR;


BKVOL=0 AND C>=UPBAND AND REF(C,1)<REF(UPBAND,1),BPK;
SKVOL=0 AND C<=DOWNBAND AND REF(C,1)>REF(DOWNBAND,1),SPK;

BKVOL>0 AND C<=MIDLINE,SP(BKVOL);
SKVOL>0 AND C>=MIDLINE,BP(SKVOL);
// 止损
// stop loss
C>=SKPRICE*(1+SLOSS*0.01),BP;
C<=BKPRICE*(1-SLOSS*0.01),SP;
AUTOFILTER;

Para diseñar varias variedades, diseña los parámetros como una cadena JSON:

var params = '[{
        "symbol" : "swap",
        "period" : 86400,
        "stopLoss" : 0.07,
        "atrPeriod" : 10,
        "emaPeriod" : 10,
        "trackRatio" : 1,
        "openRatio" : 0.1
    }, {
        "symbol" : "swap",
        "period" : 86400,
        "stopLoss" : 0.07,
        "atrPeriod" : 10,
        "emaPeriod" : 10,
        "trackRatio" : 1,
        "openRatio" : 0.1
    }]'

La estrategia utiliza una biblioteca de clases de modelos: biblioteca de operaciones de futuros de monedas digitales (versión de prueba).
