Script needed for developing trading system

Is it possible to write a script which will do the following;
Use max 3% for money management (not per order but per pair)

Automatically work out the TP based on a numerical input in the script (able to mod via metaeditor)

Have modifyable SL based on a MA and a pip gap (*)
When TP is hit, automatically close 80% of the trade leaving the remaining 20% open
The script will of course need to auto figure the 80/20 split and settle on the closest whole figure over 80%.


i.e.

3 lot = 80/20 (24mini / 6mini) (close 24 run 6)
1 lot = 80/20 (8mini / 2mini) (close 8 run 2)
.5 lot = 80/20 (4mini / 1mini) (close 4 run 1)
.3 lot = 66/33 (2mini / 1mini) (under 80% so full close)

Will need long & short versions. Double click with no options to select (all in script) just a manual verification showing open price, SL price and TP price.

(*) Another script may be needed to update the SL each day as the pip value remains constant but the MA moves so the SL changes daily. Again manual verification will be needed showing new price for SL.

Anybody think they can take that on and get it working?

You need and EA not a script with all the task required.

Can an EA be run manually and not automatically? And what about the daily SL update, can that be run from a script?

BTW, thanks for the reply, sometimes you ask and get nothing. lol.

Daily SL change would probably be best to run from the EA. And yes you can set an EA to manual so that it makes trading recommendations and requires you to confirm.

I feel I haven't made myself clear. I don't want the script/EA to make trade suggestions, as I don't believe a trading system is ever completely mechanical, and if it is, it's rarely accurate or it's retro fitted to the market.

Instead the trade selection is completely manual so that when I run the script or EA the trade is entered in whichever direction I'm working in, and the trade is then auto calculated for the money management, and the 80/20 TP with the initial SL being set based on the MA.

Then the other script or EA is run daily to re-determine the new SL based on the same MA with a popup box with the new SL written in it.

I just need the manual confirmation for everything so I can keep accurate 3rd party records.

Alternatively I could drop the initial SL part of the main script or EA and run the secondary script or EA to make the first SL as I would daily to update it.

Not sure that makes it any clearer, I have flu so it all makes perfect sense in my head, but that means nothing right now.
