Hello, I have paid to use this website for more than 2 years. Because you can't install the Google plug-in, you can't download the MT5 files of the program. How to solve it

Hello , I want to ask a question. After an open positions, partial positions how run?
for example,After an open positions, 1/2 positions use ratio 1:1（TP:SL）, 1/2 positions use ratio 3:1 （TP:SL）

The software is very good. Thank you very much.
BBS is a big help to me.
Saves a lot of programming problems.
I can focus on trading logic problems.
I now use MT5 development, run the test using MT4.

Hello, I'm using Bollinger Bands(20,2).

BUY SIGNAL

current candle high must have higher than Bollinger Bands Upper Bands.
SL is 1 PIP below previous Bollinger Bands Middle Bands.
TP is equal to the SL size (so 1:1 ratio)

SELL SIGNAL

current candle low must have lower than Bollinger Bands lower Bands.
SL is 1 PIP above previous Bollinger Bands Middle Bands.
TP is equal to the SL size (so 1:1 ratio)

Thanks in advance
