I got into trading around May 2017 after about a year of regular in a range of peer2peer (P2P) systems, commodities and stocks. My strategy was simple — every month I would invest 20% of my total income (or as much as I could afford) before tax into a range of investments, then regularly reinvest the dividends generated from interest into more investments. crypto investing The first part of this strategy came from a book called the The , and second from general modern economic thinking. The combination of the two proved quite effective and allowed me to diversify my portfolio and reduce risk over time. Richest Man in Babylon With the growing excitement around cryptocurrencies I thought I would give it a go while leveraging the same strategy. Every month I would invest about 5% of my total 20% into a range of cryptocurriencies — primarily bitcoin, etherium, litecoin, dash and a few altcoins. Overall this performed well (especially with the massive rise in value in the second half of 2017). However, recenly I could not help but think my simple strategy was not as effecient as it could be. Being the start of 2018 I thought I would put my theory to the test and try some different trading strategies on historical cryptocurrency data. I couldn’t find anything that really suited my needs online, or didn't seem to require a subscription to buy so I build something myself with python. The result of the project is git repo you can try for yourself (python 3)- https://github.com/Raudaschl/historical_crypto_trade_simulator Steps Requires pandas and python 3 Install Pandas pip install pandas Step 1 Download historical data python download.py To download the prices for different cryptocurrencies for the last 300 days as a csv file curtesy of the cryptocompare.com API. You can edit the coin types in the download.py file. Step 2 Run the script python trader.py This will produce the following outputs: — The current value of your investments assuming no trade strategy has been applied apart from holding onto your investments Original Value — The total dividends based from your initial investments Original Dividends — The total dividends based on original and new investments Final Dividends — The total value of your original investments after the strategy is applied Original Investments Value — The total value of new investments made based on your strategy New Investments Value — The total value of your investments and any dividends taken Final Total Value Step 3 — Customise Set Orders is filled with cyptocoin different orders — example: bitCoinOrders array bitCoinOrders.append({“coin”: “btc”, “buyPrice”: 2690, “coins”: 0.0782, “date”: “2017–05–27”}) : set the currency symbol (needs to be one of the currencies downloaded before) buyPrice: original buy price ($) coins: number of coins bought date: date purchased coin Calculate Function Function The calculate function takes an array of orders and examines their value from the point of purchase. During this iteration I have set up trading strategy which aims to sell 40% of the coins from a single order when that order has increased in value by 300%. That 40% is then reinvested by buying other cryptocurrencies which is in the array. If the value of the 40% sell is less than $40 then I will sell all the coins outright and claim that amount for myself as dividends. dfAdditionalOrders Variables — Set the % value where you will take profit. Setting 3 for example will automatically trigger a sell at 300% reinvest profitFactor — the percentage of the total value of the order when the profit factor is reached to reinvest. Percentage — Sell all coins of this specific order when the value hits the profitFactor and the value of the reinvestment is less than this value. minimumSellValue BuyWeightsBuild Function Function This function sets the coins to buy from the profits of any sell (see above). They exclude the coin that was originally sold so for example if bitcoin turned a profit and was sold it would not buy more bitcoin with the profits. Variables buyWeights.append({“coin”: “btc”, “weight”: 0.25}) — the symbol of the currency you want to buy (must be one of the currencies downloaded) coin — this is an indicator to how much you want to buy of one currency compared to another. The total value of all weights should add up to 1. weight Conclusions So there you have it. In my experiments I found I could only really increase my overall value by less than 1% over the last year so perhaps the simpler model is still the best one for me. Maybe you will have better luck. 💰 💸 — Git Repo https://github.com/Raudaschl/historical_crypto_trade_simulator PS: I’m not a programmer, so please go easy on me with the code 😃
