During intraday trades i use Pi as my charting software and other brokerage firm for taking trades sometimes i scalp in banknifty in 1min TF so i need to enter and exit my trade within 5mins or less.
I found Pi’s BUY/SELL window much convenient because its next to my chart but for brokerage reasons i use different platform for trades .
So my question is there any way i can add a widget or addon type in my trading software or something like fire orders without switching between charting and trading software again and again thus saving time.??
ah! you should probably just use Pi to fire orders as well. 
There is no such add on/widget btw.
