Reentrancy in TFG._transfer(address,address,uint256) (#908-960):
External calls:

External calls sending eth:
- distributeTeam(constractBal) (#944)
- address(buyBackAddress).transfer(amountToTranfer) (#1019)
State variables written after the call(s):
- _reflectionBalance[sender] = _reflectionBalance[sender].sub(amount.mul(rate)) (#948)
- _reflectionBalance[recipient] = _reflectionBalance[recipient].add(transferAmount.mul(rate)) (#949)
- _tokenBalance[sender] = _tokenBalance[sender].sub(amount) (#953)

TFG.collectFee(address,uint256,uint256) (#972-995) performs a multiplication on the result of a division:
-buyBackFee = amount.mul(_buyBackFee).div(10 ** (_feeDecimal + 2)) (#985)
-_reflectionBalance[address(this)] = _reflectionBalance[address(this)].add(buyBackFee.mul(rate)) (#987)
Consider ordering multiplication before division.

TFG._approve(address,address,uint256).owner (#897) shadows:
- Ownable.owner() (#527-529) (function)
Rename the local variables that shadow another component.

TFG.setBuybackWallet(address).wallet (#1058) lacks a zero-check on :
- buyBackAddress = wallet (#1059)
Check that the address is not zero.

TFG.calculateCooldownAmountLimit(address) (#962-969) uses timestamp for comparisons
Dangerous comparisons:
- listedAt + (7 * cooldownTime) < block.timestamp (#965)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#467-492) uses assembly
- INLINE ASM (#484-487)
Do not use evm assembly.

SafeMath.mod(uint256,uint256,string) (#307-314) is never used and should be removed
Remove unused functions.

Additional information: link

TFG.maxTxAmount (#704) is set pre-construction with a non-constant function or state variable:
- _tokenTotal
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Pragma version^0.6.0 (#39) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#467-492):
- (success,returndata) = target.call{value: weiValue}(data) (#475-477)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable TFG._taxFeeTotal (#696) is not in mixedCase
Follow the Solidity naming convention.

Prevent variables from having similar names.

TFG.initialSellLimit (#715) should be constant
Add the constant attributes to state variables that never change.

reflectionFromToken(uint256) should be declared external:
- TFG.reflectionFromToken(uint256) (#849-856)
Use the external attribute for functions never called from the contract.
