Modification of a Martingale EA

Requirements:

1. Remove any restrictions/subscription on the EA
2. Do not let the EA trade during trending market (one direction movement). You can use any sort of function you deem fit (maybe rate of change or r slope) in 3 or 4 levels of change like; (1) Avoid small change in trend, (2) Avoid normal change in trend, (3) Avoid big change in trend, (4) Do not use this option; to decide when to trade. What I want you to do is prevent the EA from placing orders when a trended market is detected and print a note (Avoiding trended market) visible above the charts. As soon as we enter a Ranging market the note disappears, and the EA continue place a trade if the conditions are right.
3. The EA has only lot size multiplier when increasing order size in subsequent trades in the martingale. I also want the option to increase the order size by a constant; say 0.01.
4. Option to enable only buy, only sell or both (default).
