[Full Test Report](https://rstormsf.github.io/oracles-presale/mochawesome.html)
Presale contract that records investor's balances and sends ether to presale owner.
It allows to set minimum Contrubution amount, start Date, end Date.

To use:
1. Flat [contracts/PresaleOracles.sol](contracts/PresaleOracles.sol) by using [solidity-flattener](https://github.com/BlockCatIO/solidity-flattener)
2. Deploy [flat file](flat/PresaleOracles_flat.sol)
3. Call `initialize` with following params:

    -startTime in unix format 

    -endTime in unix format 

    -cap in wei format 

    -minimumContribution in wei format

    -vault (eth address where funds will be collected) 
    
Example: 

    "1510291574","1610291574","100000000000000000000","100000000000000000","0x0039f22efb07a647557c7c5d17854cfd6d489ef3"

    startTime: `Friday, November 10, 2017 5:26:14 AM `
    endTime: `Sunday, January 10, 2021 3:12:54 PM `
    cap: `100 eth `
    minimum: `0.1 eth `
    vault: `0x0039f22efb07a647557c7c5d17854cfd6d489ef3`
4. Let investors send money to contract's address OR to send to `buy` method (`0xa6f2ae3a`)
