Converting MT4 to MT5 Project 2

I want to code a strategy





The 1st sell triggered at 1.12935.(0.02). Then 2nd sell(0.04),1st buy(0.02) will trigger  simultaneously at 1.12935+150= 1.13085. set take profit of 1st buy  where 3rd sell,2nd buy will trigger, 1.13085+150=1.13235. 3rd sell(0.08),2nd buy(0.04) take profit of 2nd buy where 4th sell and 3rd buy triggers at 1.13235+150=1.13385. The price should keep  multiplying by dubbed the previous price in each  time it goes against by 150. Note: set take profit only on buy in each 150. The (market should close or end when it moves dawn or sell in -300. Note when the trade is selling the last buy will be in negative and should also end at the same price sell take profit i e -300. The same strategy applied if we look to buy.
    It's very important to note that if we look to sell and buy at same prise it hit one before the other. Using the price above as an example
If we are to sell and buy at 1.13085 2nd sell (04) 1st buy(02) it hit buy before sell which will not be perfect for this strategy, it's better it hit sell before buy. To achieve that instead of allowing the sell and buy to trigger at same prise

I will send more detail like inputs, but I want to make sure you understand what I mean here
