my brooker (pepperstone) tell me that price on chart is bid price and if i want i can add ask price.
Is it possible to visualise medium price ?
thanks for your answers.
I think what the OP wants is a "middle" price "(Ask + Bid) / 2" and not a "Median" price "(High + Low) / 2". Many other Trading Applications use this approach of a "middle" price with a +offset for "ask" and -offset for "bid", instead of a base bid price as MetaTrader does and I think this is for what the OP is aiming.
Unfortunately, MetaTrader does not use a "middle" price as many other Trading Applications do and all chart data and indicators are based on the Bid Price. An indicator could mimic the the current "middle price" line on the chart, however all past data can only be represented as "Bid price" as neither the Ask price nor the Spread are stored in the history data. You will just have to get used to working with a Bid price instead of a "middle price".
Thanks a lot for all your answers.
@FMIC: you are right, it's what i wanted. Thands a lot
