Expert Advisor that can automaticaly open and close orders on London session.........and do a bit more

I am thinking off the following strategie:

Should work on all forex pairs.
Open position (with a limit (maybe 40 pips) and stoploss) in the morning at a set time each day, maybe just after London session opens.
Depending on market open a buy or sell (follow the trend).
The level of opening is the baseline for that day, al following other orders should be triggered and placed starting at this baseline level.
Our position wil go up and down and each time it crosses the baseline close the position (because if you cross the baseline it will become a loss) and simultaniously open new position in opposite direction to follow the trend with profit on other side off baseline.
So you always have just 1 open position at the same time.
Repeat this proces untill limit is reached.
Next morning repeat same proces, start the next one.
Limit and stop loss are to be set manualy in the config, so we can tune it for different pairs and market condition.
Because you always end position when it crosses the baseline the initial stoploss is accualy never ever used if the robot works correctly but it is just there for extra security.
If the limit is almost hit move the stoploss much closer (by a set value in settings) and move the limit higher (by a set value in settings), so if there is a very strong going trend you can reach much more then the initial set limit.
Robot must be fast and stable around the baseline level closing position and opening new one, the faster and preciser it can execute this the better it will work when the market is pending al the time around the base level.
Instead off opening at baseline it could maybe also work to make pending order before reaching the baseline if that is better and have this pending order triggered directly followed by adding the next pending order for when trend reverses.
Strategie is the robot should be able and reach the limit almost every day, maybe it crosses the baseline many times so profit would be the reached limit minus the spreads from opening a new position multiple times at each crossing off the baseline.

Who can build this, advice on this and make it work smoothly?
