C++/FIX Modify Existing Trading Program

Searching for a consultant with significant experience with programming experience in C++/Linux to modify an existing program. Existing program brings data in from 3 data sources (via FIX API) , written in C++ and run on a Linux Server using a g++ compiler. Trades can be made at any of the 3 sources. Need to code a simple strategy based on Order flow signals derived from data sources. Signals generate an entry and exit. Several symbols must be able to be run at the same time. MUST BE FLEXIBLE to work through several variations to find one that works profitably. MUST BE ABLE TO DEDICATE 3-5 HOURS PER DAY TO WORK ON THIS. Developer must have ample time available IMMEDIATELY to complete this task in the next week. Would like to see demo results in the next few days and live testing shortly thereafter. If you have not done a project similar to this, do not apply please. Developer must have worked on Order flow types of models for Spot Forex and Futures using FIX. This is the first in a series of development projects. This is Phase I and has price and time sensitivity. ALL work must be completed on remote Linux Server. The modifications include the following: i) Code entry signals that mimic Python code I have written. ii) Verify your code in C++ match the Python results I have or reconcile differences if acceptable. This will be accomplished through data collection and independent verification. iii) Framework for prices and trade execution exists in current program but may need to be changed for order types and symbols. iv) Program must be set up in such a way that I can make changes easily to the signals. One way is to create functions that are easily used by common procedures. For example if an entry signal is being tested, a function EntrySignalOne (symbol, parameters) can be used alongside other functions to create an entry. Similar logic can be used for an exit. v) Must document and show me what has been done so there is cross training in place. This will allow changes to be made if an emergency happens and you are not available. vi) Run in demo first and then iterations on actual trades
