This is the price at which you made or will make your first grid order of your trade. 

If you already started your trade by buying 200 $ at coin price 100$ per coin so the start price is 100$ and this is actually will be the first grid of your trade! 

If you haven't enter the trade yet and you are planning to enter the trade ( you will buy your first order grid ) at coin price 100$ but the coin price now is 102 so, the start price in calculations must be 100$ , i mean you will put the first limit order at coin price $ so you will wait the coin price to decrease from 102$ to 100$ to fill your first grid order.

This is the initial value of $  ( amount if money ) you paid to buy the first grid of your order or you are planing to pay to buy the first grid of your order. 

If you already started your trade by buying 200 $ at coin price 100$ per coin so the start price is 100$ and this is actually will be the first grid of your trade! but the initial investment is 200 $

If you haven't enter the trade yet and you let's say that the coin price is 102$ now and your start price is 100$ and initial investment is 200$ so you will put a limit order at coin price 100$ ( will be filled when the coin price decrease to 100$ ) and your initial investment will be 200$

This is the price below which you won't do any grid buying order ( also the minimum price you expect that the coin will reach and below it you want to exit the trade ) 

If you are planning to put a stop loss for your trade ( recommended ), it will be below that Min Expected price.

You could also consider it practically as the lowest price of the coin it may reach, in most cases, some clients put it as the previous support level. the support price differs depending on the technical analysis , your trading style and chart time frame so the support level will depend on the type of trader you are! long term traders takes the previous major support on longer time frames but short term trader take closer one. 

If you don't have max investment for the trade and your budget is big enough, just choose " NO " and in this case, you must input the order size multiplier for the app to calculate and grid the trade for you! will talk about the order size multiplier below!

if you have max investment for your trade which is the common case. many traders have a limit let's say just 1000$ max to buy this coin in many different prices to get the best average price, in this case, just input your maximum investment size for this trade which is the 1000$ which is logically more than your initial investment as the initial investment is a part of the max investment.

This is used to feed the model with the required number of grids so that the app will spread the orders on them.

Short term: 20 grids

Medium  term: 10 grids

Long term: 5 grids

Custom: in this case,  the number of grids input box will be enabled so please enter whatever number of grids you want! 

Concept:

The order size multiplier is how much change from each order to the following order. so, if you make the first order buying  a coin with 100$ initial investment and when the price went lower, you made the second order with 200$ so your have order size multiplier ( 200/100 = 2 ) and so the third buying grid will be with ( 2 * 200  = 400$ ) investment and the next is ( 400 * 2 = 800$ ) and so on! 

Order size multiplier could be any number more than 0. 

if Order size multiplier between 0 to 1 so each order size will be lower than the previsions order.

if order  size multiplier is more than 1 so each order size will be higher than the previsions order.

The 2 Cases:

if you have a max investment size for your trade, so don't worry about the order size multiplier as Gridit will do the internal iterations and calculate the optimum one for you and do the gridding task based on that! that's why, you will see the order size multiplier box to be disabled when you choose that you already have max investment size and you entered its value. 

if you don't have max investment size for your trade and want to use your desired order size multiplier, just choose " NO " and you will have the order size multiplier box to be enabled so that you enter it manually! 

You have to enter your desired profit percentage for GRIDIT to tell & Remind you when to exit your trade with your desired profit percentage! 

If you have a specified stop loss, please enter it for Gridit to calculate your situation at it, if not, Gridit will recommend the optimum stop loss value for you! 

It's logic that Stop loss price must be lower than the Min Expected price. 

After you added your desired inputs, just click " Generate output " and a csv file will be generated besides the app. you could simply open the csv file or just simply click" display output " and a nice window will show you the output without opening the CSV. 

it's Recommended to "reset" the app after each trial  to delete all inputs from it and you put your new inputs!
