Expert Advisor developer MT5 needed based on PSAR and MACD indicator (this might need a script)

A. MT5

B. Take only one order at a time    

C. Open an order ONLY when : 

1. PSAR changes its direction (ie: @ start of Second PSAR DOT)  

 AND 

2. MACD is in Same direction as PSAR

i.e: 

Buy : PSAR second Dot is below graph  AND  MACD previous Bar is +ve 

Sell : PSAR second Dot is above graph  AND  MACD previous Bar is -ve 

D. Closing Order only when :

MACD reverse direction ( a confirmed MACD value then we close order @ start of next MACD bar  )

For example  : For an open buy order , 1 Hour chart ,  MACD started to cross line towards negative values , then it keeps changing  +ve/-ve .. EA should wait till the end of this hour to decide  , if it closes as MACD on a -ve value > then open order to be closed imidiatly at the start of the next hour  , if it closed +ve (no action >  keep order open) 

E. Options to be included (with a disabling choice / to be totally disabled ) : 

1: close order at a certain Take profit PIP level (In PIPS)

2: Trailing stop with its parameters 

3. Stop loss at a certain PIP level  (IN PIPs)

NOTE  : any of above 3 options if enabled are still always Superseeded by main closing conidion (MACD changing direction) explained in point D above 

F: LOT size : 

1. Starting size to be configurable by myslelf as an input (starting default 0.01)    

2. LOT Size Steps for next orders ... (second ...thirds ... fourth ... etc ) 

3. Max number of orders to be executed (up to how many orders)  ( ex: after 5 orders dont take any more till i re attache the EA ) 

Example  :

I attach EA to the chart   , First order open lot size is 0.01  , it is then closed (by D or E conditions above ) , EA should wait for the next oppurtunity .. this time open order lot size is 0.02 (if i am putting LOT size steps 0.01)  , then after second order closure , EA will wait for third order lot size 0.03 once conditions apply  and so on 

Lot size cycle to restart at default ex: 0.01 again once i detach and attach again  

Prefer to have a demo version to be tested First to make sure all requiremnets are met  

I hope I have made it clear , ready for any questions 

Thanks in Advance
