Expert Advisor programmer needed

Hi there, I want to sell an EA bot, which is encrypted / secure, so that the user can only make basic adjustments.

The EA should have a number of fixed conditions (5 from memory) to open a trade: momentum, wpr, rvi, and a few more. There are 2 sets of conditions for a BUY order, 2 sets for a SELL.

The SL could be changed by the user, in fact, I'd like this to be done on a % basis, rather than pips. 

Additionally, the TP for my strategy should remain open, or possibly set to close at the end of the week, e.g. Friday 8pm GMT. Once a trade is opened, the user can add TP to their trade if wanted

The bot should operate all weekdays, between fixed times. Ideally, the time settings should automatically update dependent on winter / summer hours.

One of the few changeable variables should be risk level: 1-5%, based on SL.

Some form of account protection, draw-down limit, number of losses per day limit, might be required.

Ideally, I want all of the critical conditions concealed to the end user, but perhaps I can have access to the code to make any minute changes.

Would like the end user to only really be able to change TP, / day & time to close all trades, risk level, days traded, so a real basic interface (4 settings).

The EA's principal use is on Forex pairs, on mt5.

I would say the security of my bot, is of paramount importance. I'm not in a rush to complete, it must be correct prior to marketing. If programming takes more than 1 week, so be it.

Thanks in advance for any interest.
