Orders for indicators development - Python - closed

I would like to back test my strategy and right now my buy signal is a batch script that runs a python script that tells my ea to buy or sell. I would like my current python script built and added as variables all into my ea for me to optimize on the current strategy tester built into MT4

Changes as follows: 1) Pending order to be in the middle of the last two closed candles instead of the one. SL to be the high of the last two candles 2) Option to either include or not include spread when placing order for SL & TP 3) Option of maximum lots size. So if the pending order when reached is above this size it will not place order. 4) Remove all code and button to do with "Reversal" 5) Expire time changed
