Algo enter with fix $ risk to a given stop price

Hi, 

I am running into the issue of missing entries in smaller timeframes cause the markets pulls away too quickly for me to calculate my position size in time. 

For example, if I want 10$ risk on every positon, one position might have a 6.1 pip stop, another one a 4.8 pip stop and so on.     This means I need to calculate a different lot size for each trade to always get the same 10$ risk. 

Now sometimes while I manually type in the stop level and choose the right lot size the market might alredy pull away without me, since I have to wait for the candle to close (verify the signal) before I can calculate the lot size.

So I would need a Algo thats does this calculation and enters at market on the next candle open. It should only check if the candle closed green (for a buy), or red (for a sell) and then do the position size calculation and enter immediately. 

Since I place my stops based on Fibonacci levels, I think I would need to enter the stop price manually in the Algo. I don't know if its possible that the Algo can "see" the drawn Fibonacci on the chart and take the price of a specific Fib-level on its own, but I think this would make the Bot more and more complicated and I'm fine typing it in manually. 

Please let me know if someone can write this Algo so we can talk about the details. 

Best Regards
