Now, you have your very own PROP FIRM LOT SIZE CALCULATOR! It now has BREAKEVEN and PARTIAL CLOSURE features!
There's no need to go to other websites just to compute for the exact lot size. It also opens the trade with a click of a button.
All inputs on the calculator can be edited. So if you want to change the SL or TP or the lot size, you can do so before placing an order.
==========================================

1. SL PRICE TEXT. This is clickable and the color changes from red to green or green to red. Green means that the SL will be added to the order and no SL if it is red.
2. TP PRICE TEXT. This is clickable and the color changes from red to green or green to red. Green means that the TP will be added to the order and no TP if it is red.
3. SL PRICE. Exact stoploss price that you want to add to the order. Also, the SL price will be used for the lot size computation.

I'm really happy with this purchase and the experience. Easily add it to a pair and you can enter in all your desired values for it to determine the lot size. Then it can place the order for you in a handful of different trade types. When talking with you developer on an improvement he was wonderful to work with and adjusted quickly. Highly recommend.
