    Experienced MQL4 programmer

    United Kingdom - Last active: 5 days ago - Tests: 13 - Portfolio: 5

    MetaTrader 4 Programmer (MQL4) I'm a professional programmer with over 5 years experience in trading forex and converting / interpreting systems for Expert Advisor automation. As a Company Director (CEO) of over 15 years I always work to high standards in a completely professional and ethical manner. Being UK based, I am fully conversant with the complexities of the English language and can convey complex points in an understandable manner. All indicators, expert advisors and scripts I produce are professionally coded, tested and robust, and include the following as standard (where appropriate): - 4/5 digit broker compatibility - Automatic time zone / offset recognition - Built in error checks - Built in safety features (i.e. Closure of orders where stop loss setting fails) I have previously coded the following complex scenarios which can be readily built into future projects: - Serial number protection linked to varying expiry dates - Restriction of indicators/expert advisors to specific chart types and/or timeframes - Automatic changing of charts to correct timeframes - Lot sizing based on account risk percentages - Spreadbetting compatibility - News avoidance (eg. Stopping trades around high impact releases) - Scraping for retrieving information from web sites / RSS feeds I have developed a robust licencing system which can be encoded into any EA or indicator. It allows on-line authorization, chart and time-frame restrictions plus allows remote changing of EA/indicator settings and variables. Please ask for a demo if you are interested. All expert advisors are coded to provide for enhanced optimization and quick backtesting. As a supplementary service I can create professional looking installers and autorun front ends for installation CD's, USB sticks, etc., including the incorporation of logos and branding graphics. I also have experience writing technical manuals, creating video tutorials and preparing seminars.
