## What is 3R Calculator?

Risk management is probably the most important part of a trading strategy, without it, you risk losing your whole equity. This calculator is a great tool for any new or expert crypto trader. It will show you exactly how much you should invest in amount, percentage, and lot (unit) size.

The calculator works great on Bitcoin, Ethereum, Binance Coin, and any other cryptocurrency. You can also use it to calculate your lot sizes for traditional markets like Bonds, Stocks, Forex, and Signals. Anything that you can trade, this calculator will do the job whether you are going Long or Short!

If the position size is greater than your equity, the calculator will display all the info that you need in order to open a position with Leverage.
                
How to calculate your crypto position size
The formulas to calculate your position sizes require 4 elements:
                
1. Account Size

This is the total USDT, Bitcoin, Ethereum, or any other crypto that you use for your trading.

Include any open trade and update your account size once your trade is exited.

Example: You have 1000 USDT, and you open a trade with a position size of 100 USDT. For your next trade, you will still use the 1000 USDT to calculate your Position Size. Once your trade is closed whether, in profit or loss, you will then update your Account Size by adding the profit or loss of that closed trade.

2. Entry Price

This is the Limit price at which your trading strategy tells you to go Long or Short.

If you are entering your trade using a Market order, use an approximation of your entry price. Make it the worst entry price, like there will be slippage. By doing this, you will protect yourself from a real surprise if the market is highly volatile.

3. Stoploss Price

This is the price of your first stop-loss that would get hit if the position goes against you. If you don’t know where your stop-loss should be, learn how to determine your crypto stop-loss. Opening a trade without knowing your stop-loss is a terrible idea and will only get you rekt sooner or later.

Maximum Risk % – This is the maximum risk in percentage that you are willing to take for each trade. This is really up to you, but I would suggest that you start with a risk % between 0.5% and 1.5%.

Even if that seems pretty small, unless you know exactly the best risk per trade because you have backtested and forward-tested your strategy, 0.5%-1.5% will keep your equity safe from the high volatility of the crypto market.

Using these 4 elements, we will be able to get our position size in Amount (USDT, BTC, ETH), in percent (% of our account size), and in Units (ADA, XRP, TRX, LINK).

### 5/5 — Full lost coin recovery

*2023-08-05*

I was so impatient to carry out necessary research but i really wanted to jump on the crypto trading and investment buzz.
Unfortunately for me, I invested 80,000
GBP worth of bitcoin with a fraudulent company. I was happy to watch my account grow to 280,000 GBP within a couple of weeks. But i didn't realize i was dealing with a scam company, until i tried to make an attempt to withdraw. I made a withdrawal request, and noticed my account was suddenly blocked for no apparent reason. I tried contacting customer support, but all to no avail. I needed my money back at all cost, because i could not afford to let it go. So i tried all possible means to make sure i recovered my scammed bitcoin. I did a lot of online search for help, and tried to see if there were other people who had any similar experience. I stumbled upon a cryptocurrency forum were a couple of people mentioned that they had been through the same process but were able to recover their lost cryptocurrency, funds with the help of itech koa. So i file a report and he was able to help me get back all my lost funds within two weeks. I will recommend anybody who wants to recover scammed bitcoin, stolen cryptocurrency, funds lost to binary options forex, investment and any other form of online scam, reach out to itechkoa@Gmail.
