well I need a bubble.io ONLY application so that customers can buy stocks starting with 1 SAR( saudi Riyal ) ( fraction stock )
they choose which stock they want , it show the price for 1 share but customers can buy any amount depending on budget for example if stock price is 100 people can buy 0.5 shares with 50 SAR , or buy 0.1 shares with 10 SAR
SAR is the currency
also I want to put an option to buy bundles of stocks for example bundle A = ( 2 shares of Stock A , 3 shares of Stock B and 0.5 shares of stock X )
I need at least to show 3 bundles
each transaction has a fee of 1% of each trade value
i need to add membership icon so if they pay for membership , they will have zero fee for unlimited trades
this will need a plug in to get live financial prices .

- main purpose is to enable user to choose from stocks in stock market with current price and uses to buy any amount of shares , for example if apple is worth 100 USD per share and he has budget of 1 USD he can and enter his budget the system will allow him to buy 0.01 shares of apple according to market price
