Go only long if last closed order was sell and inverse

Can someone please help me write a simple code - if last closed order was long go only short next time and if it was short go only long.

This is to avoid reopening a new postion when the TP or SL is hit while the trend opening signal is still true.


Many thanks.

I need your help guys please, I'm not a good programer.
Here is the code it's simple, it buys when the previous candle body is above the MA and sells when full body candle is below MA.

Because I use a SL and TP, when they are hit the EA re-opens a new position as long as the candle is above or below MA.

I want to wait until the next signal is provided, which is if the previous closed trade is Buy the next one must be Sell.

Pleaaaaase help!

This is a really easy solution but it will depend on how many orders you have open in the one direction. If you are only using one, then it will be good.

I just modified your order send code. changes in Red.
