Existing ea. Add delay field and increment dynamic field for trailing SL

Trailing SL currently has; Trail start, Trail stop and trail increment.

1)      I need to add another trail control field for the user to define number of PIPs, the price must move in the right direction, once the trailing SL has been triggered, before the incremental moves commence, thereby extending the gap between price and trailing SL, before the trail starts to follow the price with the increments set.

2)      I need also an additional increment control field, allowing the user to set price movement to trail increment movement ratio. i.e perhaps user requires trail moves by set increment of 0.5pips for every 0.8pips positive price movement.

Esisting example:
Currently users sets:
Trail start 10 pips
Trail stop 5 pips
Trail increment 0.5 pips

Result:
SL moves from original set position to 5pips behind the current price as the price hits the 10pips in profit price, then moves along behind the current price by 0.5 pips for every 0.5 pips the price moves in an increasing profit direction. Holding its ground when the price revererses.

Propsed example:
users sets:
Trail start 10 pips
Trail stop 5 pips
Pips move before Increment commences 8pips
Trail increment 0.5 pips
Price move for increment 0.8

Result:
SL moves from original set position to 5pips behind the current price as the price hits the 10pips in profit price, then wits until price moves a further 8pips before the trail movement commences. Then the trail moves along behind the current price by 0.5 pips for every 0.8 pips the price moves in an increasing profit direction. Holding its ground when the price reverses.
