Trading robot writing/modification

I need to write a simple trading ROBOT in MCQ4 that executes a varying number of orders at different prices while the market keeps going in certain direction. The strategy is similar to grid trading but with  modifications. The code should amend the stop losses for all orders once certain price movements take place (similar to trailing stop order). Once the stop loss is triggered, the code should execute the trading in the opposite direction using the same approach.

The code does not involve the use of any indicators - this is a simple program that follows the price and executes certain steps based on the price level. The bulk of algorithm is written, but fully functional EA still needs to be created.

Further details will be provided to qualified applicants.
