Bookmap enables traders to trade a mini or micro instrument (e.g., Micro ES or mini DAX futures) from the chart of the major instrument (e.g., ES or DAX futures). The eligible pairs are not configured by the trader but are predefined. In case of an eligible instrument pair, the symbol box on the Trading Configuration Panel of the major instrument will include both the major and the mini or micro instrument.
To trade the mini or micro instrument off of the major instrument chart, the user must first subscribe to the mini (or micro) instrument through the Bookmap control window.
Once subscribed, both instruments will appear active in the symbol box on the Trading Configuration Panel.
Once the major and mini (or micro) instruments are active, the trader needs to click the Start button in order to trade the mini or micro instrument from the major instrument’s chart.
The symbol presented in the symbol box will be the tradable one.
Since the tick sizes of the major instrument and the mini (or micro) instrument may be different, the price clicked on the major instrument’s chart is rounded to the next compatible value of the traded mini (or micro) instrument. Using the Round box on the Trading Configuration Panel, traders can define whether to round the price into the market (TO) or away from the market (OFF).
