@jstap I think that may have done the trick, thank you!

Please note that I set this up fro trading on XAUUSD, where on my broker 10 points is 1 pip, thats why there is a x10 in the formula blocks, please remove or change this for your own set up.
@l-andorrà Thank you 
but I have some unfortunate news, it doesn't appear to be modifying the SLs when a new trade is opened 
any chance you could take a look and let me know what I have done wrong? I suspect its in the Running SL formula, can we do a numeric value minus pips?
I believe that I may have solved this, yet to be tested as its weekend and markets are closed, but here it is:

This will still open multiple trades, but the SL is set via variables, so will always be the same for all open trades(buys or sells). Buys and Sells are setup to function independently from each other so you can, in theory, run both buys and sells at the same time. This will open a max of 4 trades on each side, but you can expand this buy adding in more Check Position and Counter nodes, just remember to add counter resets in.
EDIT: I have noticed tht when it adjusts the SL, because its looping through each trade one by one, its prone to the price the changing so not all SLs will be exactly the same. There will also be slippage when it closes multiple trades at once. I will experiment with variables, the best way to do this imo will be to fully close the trade at profit, then open up a new trade thats the same lot size that the two(or more) would have been collectively, then set its stop loss to, for example 5 pips below the opening... ie, where the updated stop loss for both(or more) trades would have been.
Think i may have a working version, i was using variables to store price and add on x pips etc, but figured that this is essentially a grid that changes the SL after every new trade opens. So my initial trade sets the stop loss at the recent(bars) swing low(or high). Then if its a buy, it sets up pending buy orders at equal length away from the initial opening price. Currently have it set to 10 orders, can't imagine it will ever be more than that. I do a check position count, then adjust all the open trades stop losses accordingly when the next pending buy order is hit. Each position count runs once, so the SL isn't constantly adjusted. I have only tested it on buy orders, but I assume the sell orders will work the same?
One more thing I need to add in is to delete all open pending orders once the SL has been triggered, but im sure I can figure that one out.
Its not the prettiest design, but it does the job.
Open to having someone improve it, or add in variables etc, if it makes it better. My Fxdreema knowledge
@l-andorrà thanks for the response dont need trading view indicators in Fxdreema, I was saying that my trading view indicators give me the buy/sell signals and I execute them with buy/sell buttons that I have already setup in fxdreema.
What I need help with is the cascading system for after I have placed a trade... so I press the buy button and it opens a trade, now I need the ea to manage the open positions
p.s. This is what I have tried, but its not really working, seems to still use the initial trade SL and not set a new one. It just uses a baisc rsi cross above 70 to open a buy position.
@l-andorrà Jumping in on this as I also have a great entry strategy, but would love to know how to do this... I have some experience using variables, but if you could give me the pseudo code of how to do this with block names I think I can figure it out.
Currently all my indicators sit in Trading View, so I just have a Buy and Sell Button on my MT5 chart which works out lot size based on % of account, hidden SL(50pips) and TP(100pips). Nothing fancy.
So the initial SL will be 50 pips with a TP of 100 pips, then once the price reaches the TP open a new order of equal value, move the global SL to 5 pips below the new order and global TP to 20 pips above... then repeat till SL is hit.
Any assistance would greatly be appreciated.
@roar That worked! Excellent! Thank you 
@q8carpenter Thanks for the response, still getting 0.00 as TP so doesnt look like it worked 
Hello everyone First question I have here, but just wanted to say thank you to everyone for answering questions on the forums, I have learnt soooo much just from previous replies
I am busy creating an EA that bases its TP on risk calculated from the previous 5 bars. The SL is calculate from the trigger bar(candle position 1) so thats not a problem, but the TP(for a sell) is calculated from the high of the trigger candle +3 pips minus the low of the previous 5 candles -3 pips.
I have created a variable and have used the formula block to calculate the value, but it doesnt seem to executing correctly when I run back tests.
Any help would be greatly appreciated.
