modifyPosition

ctx.order.modifyPosition(params)

At a glance — adjust the stop-loss and/or take-profit of the open position without closing it. The go-to for moving a stop to break-even or trailing it. Returns an OrderTicket.

Signature

modifyPosition(params: ModifyParams): OrderTicket

ModifyParams lets you set either or both of stopLoss / takeProfit as a PriceLevel.

Example

order/limit-and-cancel
import { defineStrategy, type OrderTicket } from '@nexpips/sdk-trading';


/**
 * Ordres en attente : poser un `limitBuy`, l'annuler (`cancel`) s'il n'est
 * pas rempli en quelques barres, et resserrer le stop d'une position ouverte
 * (`modifyPosition`). Le `limitBuy` renvoie un `OrderTicket` opaque à conserver.

export default defineStrategy({

            pending = null;
            barsWaiting = 0;
          }
          return;
        }


        if (ctx.position.isLong) {
          ctx.order.modifyPosition({ stopLoss: { type: 'pips', value: 10 } });
          return;
        }


        if (ctx.position.isFlat) {
          const limitPrice = ctx.bar.close - 0.001;
          pending = ctx.order.limitBuy(limitPrice, {
            riskPercent: 1,
            stopLoss: { type: 'pips', value: 20 },
            takeProfit: { type: 'rr', value: 2 },
          });
          barsWaiting = 0;
        }
      },
    };
  },
});

Tighten the stop once the position is open.
