I found solution
If you want to have monday open time the same as friday close
you have to edit the history data
-press F2
-find your currency cross
-add date -> sunday
-edit the newly added day by entering OHLC data the same as friday close
and you have sunday data opening the same as friday close.
It will trick your indicators and they will be using the right opening price, note the indications and when monday comes use them instead of the one that brokers will feed U

because they don't match the friday close and the indicators show false signals (in my case)
Today it cost me 100 pips on GbpJpy and UsdJpy (compare the friday close and monday open of those pairs and you will know what I mean)
It is useful for someone who trade D1 (like me)
and for someone for who open data is very important (like me)
For daytraders it doesn't make any diffrence I think.
I hope someone will find this tip usefull
