Just started to create a small trading terminal its in begining stage once completed i share the final output, if you find any improvements please share your thoughts . In present terminal 550 x 550 tinker ui size to that easily placed on running live dhan charts .
features
watchlist add nifty , sensex options.
place , modify and cancel orders.
position: convert and exit single click.
still some improvements needed checking any lags or stuck in real time.
i will add dark theme also, testing takes some time, i want to add some features based on feedback from forum members any visual like you said dark theme and other related to trading if i missed. Then i can test for hang, crash, stuck like that after adding features based on requests and role -out testing to users.
Buy with target sell and vice versa added to add stoploss need live LTP websocket feed which is data api, i am presently testing in keeping view of normal free trade api, the other possible solution is superorder, so share your views friends, i try to improve it.
added target live monitor window to monitor and cancel like mostly works like postion tab but shows open ones.
back in the days i used to use this tool made in python for some other brokerage. it was almost a full fledged options trading tool for me. it had everything. managing positions, watchlist, basket orders, grouping. also available margins, selective exits and entry for individual legs. with live prices of Nifty and BNF on top left portion etc.
sharing few old pics of that tool which i found. maybe you can get some idea from it.
